I did something similar for an SO-50 demonstration at a
hamfest a couple of years ago, using two Baofeng HTs with
an Elk log periodic. You can see pictures of this setup in
a video I posted:
I used a UV-82 for the uplink, and a UV-5R for the downlink,

not experience desense with this setup, and made a good
number of contacts during this demonstration. I had to use
the diplexer with my Elk, with only one coax feedpoint, but
the diplexer also served as a good bandpass filter for the
