Re: [Repeater-Builder] Re: Bad adapter
Must be that because splices were/are very seldom used, the prices are astronomical. I will wait, for now, till I see what the future will bring me. By splicing only where the cable can be well supported on both sides of the splice, I would anticipate no problems using what I have. And at least two of the connectors I have will be used with the heliax, so can't sell em all...

Re: Re: [Repeater-Builder] Re: Bad adapter
I could put the splice in a section of PVC large enough for the connectors, depending on the situation. I was looking at the cables on the local fire departments tower, and what a mess. Cables held in place with chunks of baling wire. One piece of cable flopping around in the wind, and no idea as to where it was connected. There are an odd assorment of antennas up there, including 2 4 bay folded dipole assemblies. I am joining the Volunteer fire department with an eye to helping with communications and other things that I can manage. One interesting item, only saw it through a shed window, is a, MTR2000 and a set of duplexer cans. Hmm, I still have my good old standard Motorola key... It will be a while before I know what I will or won't be allowed to do. Another project may be finding out if the siren on the tower can be repaired or not. Could be something simple. That could be top priority. The tower itself is 27 meters tall according to the info on the FCC web site. maybe 85 feet, give or take... If I were to get permission to put my repeater there, and the antenna on the side of the tower, I would not be cutting the Heliax other than needed there. But would be sure to get something better than baling wire to hold it in place, ha ha ha...

RE: Re: [Repeater-Builder] Re: Bad adapter
Ron and Wayne, I have several of those splice connections from a job where I got to remove old Heliax on top of a building. They make them to go from the same size cable to others also. If you have 1 5/8 Heliax you can convert to 7/8 or 1/2 inch but be warned, they may be expensive. They are much better than going through a regular N connector. I still have all of them that I took down, just have never needed them on my tower, yet. I have several 300 and 400 foot pieces of 1 5/8 Andrew Heliax that I may have to splice together to get to the height I need. So far, I have yet to buy anything new in the way of Heliax for my tower except the snap-in hangers. Grin, I am cheep.

Re: Re: [Repeater-Builder] Re: Bad adapter
Did some searching, and it looks like splices would run maybe twice or more the cost of one male and one female. I found about $30 or so, maybe more, I forget, just for the inner part, and the only shell I found by itself was out of sight. A splice for larger Heliax seems to be around $129.00. As it is, I have 4 male N connectors for the 7/8 and one female. Figure I will never need all of them, being as I have them. If I did not have at least one more than I figured, I would wind up needing to find another one. Murphy's Law seems to work that way. Like those end caps for PVC pipe. I always wind up not having enough of them unless I buy the big package, which Home Despot never has when I need to buy them.

Re: [Repeater-Builder] Re: Bad adapter
For the record, the Andrews web site seems to still be down. Means all info I fiond is from other web sites, vendors, etc... Also, it seems that Andrews has discontinued a couple of types of Heliax, including what I have. One person came up with them only making it with aluminum outer shield. Not true, they are making both aluminum and copper types... Still looking for info on connectors and loss. If anyone has the andrews catalog in pdf, would it be possible to either email it or upload it somewhere so others of us could obtain it? Thanks...

Re: [Repeater-Builder] Re: Bad adapter
you wont notice the loss... My club just Put up a New antenna and New 7/8 hardline. the hardline was about 200 feet. the Tower Guy dropped a knife. 1 in a million shot and cut the hardline at the base of the Tower. I spliced the cable using 2- 7/8 EIA flanged Connectors because that what I had available in my truck at the time. taped it up. No Noticable loss at all. Tested with a network analyzer showed a Very small almost un-noticable bump in the cable where the splice was. If I worried about insertion loss at Every Connector I would give up owning 6 repeaters. Of course you have you use high quality connectors. The worst Connectors are 90 degree connectors. they use a Cheap spring inside. that heats up and opens like a Fuse over time.

Re: [Repeater-Builder] Re: Bad adapter
Okay, at this point, I have the following: 100 feet of LD5-50A 1 Female 'N' connector for same 3 male 'N' connectors for same, plus an additional male 'N' from another source. All for the LDF5050A cable At antenna, a 3 or 4 foot 1/2 Heliax jumper, as the connectors for the 7/8 Heliax are a tad too large to fit the antenna base. Antenna on a 23' tower, and about 21 feet up to the end of the jumper, which will be used with some bow to allow for possible movement and being able to clamp the 7/8 to the tower so it won't pull on the jumper at all. I also have a bulkhead mount Polyphaser which I could, for the time being, install at the repeater itself and use a jumper there that is RG214, currently between two cans on a 2 meter duplexer. Two foot, long enough to exit the bottome of the repeater cabinet and connect to polyphaser. I figure about 30-35 feet of the Heliax to get to that point, and allow a bit of slack in the RG214. it would be simple to use one male and one female 'N' connectors to splice the Heliax if I move things later on. Some of these connectors might be harder to get later on, and at a maybe higher cost that I got them for. Low calorie budget from here on, spent too much on the rep[eater already.

LOL! Second, looks like the Heliax could be spliced back together with proper connector(s), but would be a job and a bit of a bump in loss? Amphenol actually does make a (relatively expensive) hardline splicing kit. Works well, according to the club techs who had to use one once on one of our runs of 7/8 that was damaged. I actually have a question here about loss. What would be the loss in one male and one female 7/8 N connector for Heliax? My thought is with the idea of possibly moving my antenna in the future, if I can eventually manage a taller tower. If you can't do new feedline for the whole run, get a splicing kit and not connectors. Better yet, consider it part of the cost of moving and don't move if you can't replace the line. That'd be my take on it. Build to commercial standards, or don't build... you'll only be back later fixing it... like anything else hammy I've ever seen/dealt with.

Larry, I thought the same thing except I would go for more 240 V...a good old TV transformer with about 800V would do.

Re: [Repeater-Builder] Re: Bad adapter
Use of the antenna could be considered theft of services IMO. Theft of services covers a number of things. Not sure what the 240 volts would do, maybe burn out loops in the duplexers being used, if it managed that before kicking the circuit breaker. Possible melt some of that teeny coax the moron was using, ha ha ha... Besides, I thought the offenders cabinet went over the side???

It'll offer some protection just stuck on the feedline and maybe protect your investment if you have a GOOD ground available for it inside, but by mounting it inside, you're allowing the lightning IN. You want the lightning OUT. But what you really want is a lightning protection system that allows the entire system... the tower, the feedlines, the cabinets, whatever... to rise and fall at the same potential. That said, having it is better than not, I suppose. There's been so much written on the topic, and done by pros, that I won't even attempt to elaborate further. Polyphaser has some excellent information on their website. Since you said the tower is 22', you're probably not at a commercial site. If you were to pull the trick of bypassing a copper entrance panel and bringing that polyphaser inside, you'd definitely piss off the other people around you inside a commercial setup, done right. At home... all bets are off. Most people don't even have their tower grounds bonded properly to their house safety ground, etc. And when they do, they often find they've created problems for themselves at HF, since the lengths (especially from 2nd floor ham shacks) are resonant at HF, which will drive you batty... ARRL Handbook and Antenna Book both have some discussion of grounding techniques also... for that late night insomnia... but if you ever get a chance to see a really well done commerical antenna site -- go get a tour. It's impressive. (And expensive.) Nate WY0X

Re: [Repeater-Builder] Re: Bad adapter
I finally got a new connector and jumper cable installed last week on a repeater that has been out of service for several months. The hard line and jumper had been cut with an ax and removed for scrap copper. It has taken me this long to find a connector for the hard line. They climbed a chain link fence with barb wire on top to get to the tower, and also removed the signaling wires to the switches (railroad) for the scrap copper value.

Re: [Repeater-Builder] Re: Bad adapter
Looking at the pictures gives me a couple of ideas. first is that the person who cut the heliax must be really dense to think he could get away with it. All one needs to do is trace that other coax to wherever. Plus it might be possible to lift fingerprints from the heliax. Second, looks like the Heliax could be spliced back together with proper connector(s), but would be a job and a bit of a bump in loss? I actually have a question here about loss. What would be the loss in one male and one female 7/8 N connector for Heliax? My thought is with the idea of possibly moving my antenna in the future, if I can eventually manage a taller tower. I see all kinds of loss calculators for cables themselves, but no mentions of same for assorted connectors.

RE: [Repeater-Builder] Re: Bad adapter
FWIW, we installed a splicing kit at our site last summer to replace a piece of damaged 7/8. The loss was negligible, especially compared to what it would have cost us to replace an additional 250' of helix. If money were no object, I'd go for a brand new mother-run of 7/8, but since they do call this AMATEUR radio, sometimes we've got to accept the next best thing.

RE: [Repeater-Builder] Re: Bad adapter
While investigating a problem with a Low-Band (46 MHz) repeater, we determined that the antenna harness on a DB 212-4 was bad. It turned out that two UHF female T connectors were bad. The center pin of the T was, instead of screwing into the center of the through pin, making contact with the aid of a little metal spring. It had rusted so badly that the spring broke in several pieces when we took it apart. Can you imagine this being used on UHF frequencies? The spring would act either like a choke or a resonant circuit with stray capacitance. Needless to say that we replaced them with the proper T's. 73, Tony VE3DWI --- In Repeater-Builder@ mailto:Repeater-Builder%40yahoogroups.com yahoogroups.com, Steve Peg [EMAIL PROTECTED] wrote: I recall a problem with a UHF repeater with terrible desense that I had some 30 years ago.

Needless to say it didn't work. Replacing that thing (which I still have) corrected the problem and it ended its service life with my repair. Steve KB3FPN
