[Repeater-Builder] Re: 6-m Very Heavy Duty Antenna For Repeater Use

Multi band antennas with certain types of problems can and sometimes do change radiation angle. And those problems don't necessarily give a bad SWR reading. In the case of the original (first production run) Hustler G6-370R there were design to actual production changes, which ruined the

Re: [Repeater-Builder] Question on portable repeaters

Peter, I haven't seen this mentioned, but perhaps you could do a split-site repeater, with a 2m rcvr, basic controller, low-power UHF transmitter and small solar panel ready to hang on a utility pole somewhere, then park the SUV with a UHF link receiver and 2m transmitter a half-mile away but l

Thanks... I have never heard of Kreco antennas. We put a DB-201 up this evening and the repeater is working just great! The diamond is gonna have to come down for an autopsy... I don't understand why the sitemaster was showing I had a good antenna when it clearly was not radiating anywhere usefu

RE: [Repeater-Builder] Question on portable repeaters

Peter, The only viable solution for a portable repeater on 2m is to use two widely-spaced frequencies, low power, and a compact base-station duplexer. Here in Central and Southern California, TASMA has wisely set aside two frequencies (144.930 input and 147.585 output) exclusively for temporary po

Re: [Repeater-Builder] Question on portable repeaters

Because the spacing between antennas is minimal at 440 and 900 megs and you can buy a duplexor for roughly the same cost as a good mobile antenna. If you want this to be an easy set up 44O is the way to go. Might also want to look for some used 2 meter stuff with duplexors ready to go. The seper

Re: [Repeater-Builder] Question on portable repeaters

Two antennas on 2-meter isn't exactly doable, the vertical and horizontal spacing issues would make it prohibitively undoable for a mobile repeater platform. You might find a mobile duplexer with 1.2mhz spacing (I remember someone here on RB talking about such a unit some time ago), but like Chuck

About 30 feet vertical, depending on filtering and the antennas. You'd probably be better going on UHF with a mobile notch duplexer.

No worries. They have an SUV roof. Vertical and horizontal distance with be significantly different, with vertical being smaller. You should look onto a mobile duplexer. They are relatively cheap. Michael -Original Message- From: DCFluX Date: Wed, 7 Oct 2009 16:18:32 To: Subject: R
