Hi Greg.
Most decent VHF transmitters will already have a pretty good LPF on the
output to reduce the harmonics.

The original article said it didn't matter, but I put a 50 Ohm load on
mine just on General Principles.
I HATE seeing a port like that unterminated!

I also tilt both of my Yagis so they're 45* to the boom, which makes
them 90* to each other.
Yes, I lose some signal on terrestrial use, but ti helped cut the
coupling, and

This will reduce the third harmonic which is causing your problem.
Good luck,

I also tilt both of my
filter on the two meter transmitter.
A diplexer will work well for this also.

I know this has been answered before, but I forget. Given one Diplexer, is
it better to put it on the Tx side to limit the 3rd harmionic going out, or
better on the Rx side to limit the VHF
