 Hi Mike,
    Sorry I was not more specific, about the setup. I am only using one
radio, Yaesu FT736R, with outputs on 144,222,432,1296 mhz. To save on the
cost of running separate feed lines for each band, I use the 2
triplexers. Taking the output on 144,432, and 1296 feeding them into a
triplexer in the shack. Then into the LMR 600 and up to the second
triplexer on the tower, which feeds the separate yagis. The 222 gets a
separate feedline.
   I know its not the best set-up, but it works.

                73  Matt   W3UUM
