I just bought an Icom PW-1 solid state kilowatt amplifier.
On my tower, I have an HF multiband antenna that is rated for 1200W, but
8' above it on the top of the same mast is my triband (2m/70cm/23cm)
vertical.

My question (being new to the kilowatt club) is what proximity concerns
might I have? I have a 2nd roof mounted mast about 30' away from the
beam with a discone and a 6m-70cm log antenna on it.

To put it simply, is there a minimum distance I should keep other
antennas away from the main HF array? I would prefer to not burn out the
front end of any of my other radios.

Any experiences or advice on this one?

Thanks,
Pat, VE3PMK
