Hello Tom
Recently, I finished another homebrew cavity preamplifier and I have been trying it on my homebrew Arrow. Its performance has been wonderful! It allows me an excellent full duplex capability and I have received AO-27 until 1 degree!
My current portable setup is a homebrew Arrow, a homebrew 70 cm/2m dawn converter, two 2m HT Kenwood TK-270 and the homebrew cavity preamplifier.
Thanks very much to Domenico, I8CVS who gave me this great project.

Has anyone used a preamplifier in a portable setup based on an Arrow cross yagi? Concern is whether there is enough isolation on 70 cm input from the 2m harmonics. ARR. Told me they would not recommend this setup. What you all think?
Thanks,
Tom, N5HYP
