[Repeater-Builder] 2 repeaters on 1 antenna
With the talk of 2 rx'ers on one antenna...what about this; I have purchased a RC210 for my repeater. Here is what on the repeater; GE Mastr II UHF running 60 watts out of cans ARR preamp DB420 at 190' TM-G707 remote base Diamond Tribander at 125' (for remote base) Moto. B/R 1500 series cans I am wanting to stick a low powered UHF repeater on the same antenna. This would be an optional control rx'er for the main repeater but will run full time ISS audio (when FCC approved). This would be on the 3rd port of the RC210. The low power repeater would probably be in the 442.000 range at about 5 to 10 watts. Would run one of the small mobile duplexers. I have heard about multi-couplers, etc. but not sure exactly what I will need to make this happen. 2 questions 1) How much desense will this cause? 2) What equipment will I need to make this happen (multi-couplers, etc.) and what to expect on cost? There is the ATL Hamfest coming up this weekend and will want to pick up parts then. The other repeater will be stuff I have. (GE MVP, PPL6060 or 599's) Ideas?

A receiver multicoupler and transmitter combiner system is usually quite expensive and lossy. Depending how far/close the involved freqs are too, this factors into the amount of loss as well. As for duplexers though, you don't need 'em with such a system. To get a better idea of what's involved in such a system, here a couple of links that may useful. http://www.rfsworld.com/index.php?p=23 http://www.anglelinear.com/couplers/couplers.html (BTW, AngleLinear makes some of the best stuff on the market, IMHO) Ken -- President and CTO - Arcom Communications Makers of state-of-the-art repeater controllers and accessories. http://www.ah6le.net/arcom/index.html AH6LE/R - IRLP Node 3000 http://www.irlp.net Yahoo!
