RG214 is good for this and you can still find short pieces on e-bay. It is double shielded silver plated braid. Bill N4XIR.

Yes, but if the receiver/transmitter used isn't well shielded, the double-shielded coax does no good. This is a big problem with using HTs for tuning duplexers, as most are poorly shielded. Bob NO6B
Fans (was Re: [Repeater-Builder] Re: Henry Amps)
A constant spinning fan makes unnecessary noise, Compared to the building air conditioning/vent fans, I can't even hear my fans. I've visited many locations without AC or vent fans running in winter time and even summer time. consumes energy A little, perhaps as much as one or two tube filaments. Most tube filaments require quite a bit more energy compared to a relatively small DC 4 or 5 inch Square Fan. and wears out much faster. Perhaps. I find it easier to just let them run replace them when they start to show wear than design increased complexity failure points (thermostat/connectors/wires) into the system. The complexity of the changing the Kenwood TRK-750 or TKR-850 Repeater Fan to operate when the power amplifiers heat sink reaches reaches x-value temperature is a mouse click in software. life will go on... s.

Bite Blocks for the Mouse and all will be quiet... I also find the bite blocks to be the best solution. Even better: don't leave any holes for the critters to get into your cabinet. I've always used bulkhead N feed-throughs for all my cabinet RF I/O, a cabinet-mounted power cord inlet. Never seen as much as a bite mark or rodent dropping inside the cabinet. Sometimes one is not lucky enough to park a cabinet at a commercial radio site... you might get a limited amount of rack space where things are more open. And at American Tower Sites... they often supply the rodent problem as part of their poor maintenance and customer service policy. s.

Re: [Repeater-Builder] Re: mouse debate 101
I used to have about 50 cellular sites that I maintained. One of the biggest rodent control solutions was to throw out all the trash cans at all the sites. That ended the problem of half eaten Big Macs and all other foodstuffs from being left at the site. That made a big dent in the rodent problem. With no place to throw out the garbage people usually took the trash with them. 73, Joe, K1ike
RE: [Repeater-Builder] Re: mouse debate 101
Good advice, Joe. Besides food, rodents also seek water. An air conditioning unit that drips condensate water onto the ground will also attract rodents. One solution to that problem is to capture the condensate before it hits the ground, and channel it 100 feet or so away from the building in pipe. Cover the open end with a stainless-steel scouring pad or other means to keep bugs and other pests from crawling back up the pipe. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of Joe Sent: Thursday, December 24, 2009 1:23 PM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Re: mouse debate 101 I used to have about 50 cellular sites that I maintained.

Re: [Repeater-Builder] Re: mouse debate 101
...not to mention reducing the odds of having a bear problem! As for the trash cans, anticipating human behavior can be interesting. Years ago, one of the big ham repeater sites in the southeast US actually had a few commercial tenants, which is generally a nice arrangement financially. The site had an ATV repeater equipped with multiple cameras at the site which could be switched to the repeater output. One night, during an ATV net with several dozen people watching the site-cams, the one inside caught a tech for one of the commercial tenants taking a leak out the open door of the shack. I'm not sure this guy would have taken his trash with him. 73, Paul, AE4KR - Original Message - From: Joe To: Repeater-Builder@yahoogroups.com Sent: Thursday, December 24, 2009 2:23 PM Subject: Re: [Repeater-Builder] Re: mouse debate 101 I used to have about 50 cellular sites that I maintained.

At the bottom is the link to the Desktrac article, which contains basic interfacing info and Desktrac programming. Mike WA6ILQ
