Try using a dual amp. And dual antenna then you won't forget to switch. Just my 2 cents Ki4ljm Marc Lonstein M.O. Unlimited Inc. P.O. Box 5364 Fort Lauderdale, FL 33310-5364 Ph: 954-720-9200 Ph: 561-368-3557 Fax: 561-368-1885

Given that I know what I am capable of and this type of system would lead to muliple failures by me as I failed to remember to switch things. If it was me I would just move the coax connectors as I swapped radios. I have done something like this in the past and got irritated and tossed the whole thing is favor of a wide band type of amp, which also has its issues of tuning and retuning --- On Wed, 2/24/10, Lee Pennington <localjunkpedd...@gmail.com> wrote: From: Lee Pennington <localjunkpedd...@gmail.com> Subject: Re: [Repeater-Builder] dual band convertacom To: Repeater-Builder@yahoogroups.com Date: Wednesday, February 24, 2010, 9:07 AM Not why............................ but WHY !!

In my car I have an old Genesis series convertacom connected to a dual band Comet antenna. I often will swap my VHF and UHF HT back and forth and utilize the dual band capability of my antenna. It works pretty well. What I would like to get some input on however, is how to run some power with this setup. Of course the easiest would be to get a amateur dual band amplifier, but I already have a VHF and a UHF (N1275A and N1274A) amplifier. What I would like to do is parallel these two amps with some kind of switching/duplexer setup so that I could easily switch from VHF to UHF. My initial idea was to run an antenna switch from the convertacom to the amps so I can manually select which one the signal goes to. Then on the output side of the amps I thought about using an antenna duplexer on the output of the amps to feed the antenna. I was also thinking of running a switch to alternately select which amp was receiving DC power, but I don't know if that would be necessary. (Could I leave both amps powered on in this situation?) So, does this sound about right or am I going off the deep end? Thanks Albert -- "Always drink upstream from the herd."
