[Repeater-Builder] Re: FSJ2-50 with PL259
Excellent, I talked with my local cable maker, and he made me a 6 foot FSJ2-50 jumper with Amphenol silver PL259s. I will pick it up on Monday. There was no need for expensive $30 connectors. If I like this FSJ2-50 cable with Amphenol PL259s, I will probably eventually replace all my cables with this product regardless of band or use. Thanks to everyone for their advise, Howard --- In Repeater-Builder@yahoogroups.com, Jeff DePolo j...@... wrote: Depending on the PL-259 in question (i.e. who manufacturered it), sometimes you can get them onto FSJ2 without any problem, other times you need to take a bit off the threads to get it to thread onto the shield. But to complicate matters, some PL-259's are manufacturered such that the ID in the area where the solder holes are located is too small for FSJ2, in which case, you can't use those, unless you just thread them on up to where the ID tapers down, and then sweat-solder the shield to the PL-259 from the rear (i.e. you won't be able to solder through the solder holes). The center conductor fits into the PL-259 pin no problem regardless of manufacturer. Bottom line - try a few PL-259's and stick to manufacturer that works. If I could remember which ones do or don't fit I would tell you, but to be honest, I don't use PL-259's very often, so when I do need to put one on FSJ2, I usually just try a few until I find one that fits... --- Jeff WN3A -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of Howard Z Sent: Tuesday, May 04, 2010 10:18 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Re: LDF1-50 with PL259 UG-176 ?

[Repeater-Builder] LDF1-50 with PL259 UG-176 ?
Hi, I have read that one can put plain low cost PL259 connectors on FSJ1-50A Andrew 1/4 inch suplerflex using a UG-176 reducer. Can the same be done with the Andrew LDF1-50 1/4 hardline? The local business I usually use for building cables is only aware of the possibility of doing this with the 1/4 inch FSJ1-50A super flex cable, and not on the 1/4 inch LDF1-50 hardline cable. Howard
[Repeater-Builder] Re: LDF1-50 with PL259 UG-176 ?
If this helps, the spec for LDF1-50 diameter over jacket = 0.345 FSJ1-50A diameter over jacket = 0.290 So assuming the jackets are the same thickness, then LDF1-50 is .055 larger in diameter than FSJ1-50A. Howard --- In Repeater-Builder@yahoogroups.com, Jeff DePolo j...@... wrote: How about doing it without a reducer at all then? According to this the dielectric size of RG-8 is 0.285 and LDF-1 is 0.29 Cant find the dimensions of the shield of RG-8 but it brings the size of LDF-1 to 0.30 which should fit nicely inside a PL-259. Just calipered (is that a word?) a PL-259. 0.37 ID to the tips of the threads, so there will still be some play if you used it on LDF1 without a reducer. I guess you could fudge it with a lot of solder, or use something else to shim it up. --- Jeff WN3A

Some of the MSR2000 had a power supply in them to charge a battewry pack and when power went out, they would then run off the batteries...there was a connection on the side of the unit near the antenna connection..So not sure if you have this type of unit Howard K2IMO

[Repeater-Builder] Re: 147.435 Repeater in Simplex Channels Contrary to Part
Not too long ago there was a posting that there was a repeater on the so called simplex freqs on 146 and 147. I posted an answer that they were legal as stated by the ARRL in the Repeater Directory. For those that think part 97 says different should read what the ARRL says. I don't think the ARRL would publish false info about the freqs. The Repeater Directory makes no distinction as to what areas are allowed to use these freqs for repeaters. Read the section in the book under Band Plans and then go to the freq plan for 2 meters. Be sure to read the foot notes Ant area can use these freqs for repeaters. Howard K2IMO

[Repeater-Builder] Re: Which coax cables to use with repeaters?
What about LDF4-50A coax cable? Is it a better choice than FSJ4-50B? Howard --- In Repeater-Builder@yahoogroups.com, Jeff DePolo [EMAIL PROTECTED] wrote: I think this is, or should be, a repeater-builder FAQ. Foil+braid cables like 9913, LMR-series, etc. should generally NOT be used in duplex environments. Although a few may report results to the contrary, braid-over-foil cables produce noise due to the dissimilar metal contact, particularly as the cable ages/weathers. As such, they should be avoided. Double-silver-shield cables such as RG-142B/U or RG-400/U are RG58- sized cables good for short runs at UHF and below. Their use at 900 or above should be kept to very short lengths and/or power levels under 100 watts due to the losses involved. RG-393 is slightly smaller in diameter than RG8 and is constructed using dual silver braids like RG-142B/U and RG- 400/U, so it is good choice for longer runs and/or higher power levels. RG214/U is also a good choice except at very high power levels as, unlike the others cited above, it has a solid polyethylene dielectric instead of teflon. RG-223 is a smaller version of RG-214, again with a double silver braid and poly dielectric. Be careful when ordering RG-214's. There are commercial grades of RG-214, as compared to mil-C17 types, which have bare copper braids instead of silver plated. Bare copper braids, even if double-shielded, should be avoided for the same noise-generating reasons as in the case with foil+braid cables. Solid-shield cable such as Superflex-type Heliax (FSJ1-50A 1/4, FSJ2-50A 3/8, FSJ4-50B 1/2) is the best in terms of both loss-versus- size, lack of duplex noise, and shielding properties.
