    True, the doubling of power (from 150 to 300) isn't gonna do much at all. However, he's stuck with the 300 watts output because of the radio. For now. How many feet of RG-58 would it take to attenuate... ;)

    That Arrow antenna has a claimed gain of 9.7dBi. :chin: Even if a bit of a high claim, that's a big help. Typical 10 element Yagi instead would be what, maybe 11-13dBi? Arrow antennas are pretty damn good, so that is decent. all by itself.

    Another Arrow Yagi "stacked" with a power divider is "yet another" 3dB, and would split that 300 watts. No more power issues, and gulp, more gain. Of course a phasing harness would split the power and give even more gain if carefully designed.

    But hell, the combination of 150 watts and the Arrow should do quite well.
    Two of those Arrows with 300 watts would hurt people. Eh?

    Always go for MOAR POWER (gain)!

    100 feet of RG8X would work as a coax attenuator. If you have it laying around, or can get it free/cheap. Some of the cheaper stuff is rated 150 watts at 200 MHz, the better stuff is rated at 360. Pushing it a little. Should get about 3-4 dB loss with that. Of course, measure the power after hooking it up to make sure.

    Worth trying if it's cheap/free. Hook up a whole roll of the stuff.

    You'd need the ability to easily switch it out of the circuit on receive.
