Hi Jeff, I did a check on the can with the original stub, it had a broad notch at 238 MHz (in addition to the tunable smaller notch at the 154 mhz). Looking at the Spec analyz with the trk gen, it looks like the starting level is 0 dB, then drops as the notch appears, then comes back, but

This isn't the most difficult question to answer, and I figure it can be answered relatively easily. I currently over the past few weeks constructed a GMRS repeater for my neighbor hood to use. It is constructed of 2 maxtrac radios one set at just 30 watts tx. I plan to use 2 antenna's so no

If it were me, I'd mount the Celwave on top and use the Heliax on that antenna. The top antenna being your receive antenna. The 1/4 wave antenna would be for transmit. I assume it has a ground plane kit (sounded like you were using a mobile antenna). Feed that with something other than 9913 or

Receive antenna should be the highest, but 40 feet is probably not enough isolation. How far do you need coverage for the repeater? It would be cheaper to use a duplexer and then you can have the best of both worlds. Good receiver and good transmitter range. Butch, KE7FEL/r To:

Trying not to start a flame fest, but done right... this sounds like a job for one of those cheap flat-pack mobile duplexers if you bring the power down a bit. Then use hardline to feed the cellwave and forget about the 1/4 wave altogether. 30W is WAY overkill for a neighborhood. At 40'
