Dave,
You're probably right that the new location probably makes up for a lot.
Have you been able to confirm that the antenna still works up at it's
rated freqs?
How much feedline loss are you dealing with? Most 'good' sites have
significant feed line runs and therefore loss. While I haven't

What ever the radiator is one word springs to mind
which if adjusted correctly makes the harness much less important and explains

Dave,
Is this a 154 MHz colinear antenna you are wanting to use on 146 MHz or
one like a DB 224 with 4 exposed dipoles?
If the 4 exposed dipole type, just what makes you
t; when an antenna made for 154 MHz is used at 146 MHz and how do you
expect to tune the dipoles without compensating for the harness impedance
matching sections mismatch also.

Norm,
Whenever I install an antenna that uses molded "Y" joints, I take the time
to seal them with 3M Scotchkote electrical sealant. I also ensure that all
nuts are tight- a few new antenn

Hello Dave,
You may be able to improve the VSWR match, but the antenna may still not
perform well. What kind of an antenna is it? If it is the typical
fiberglass collinear antenna, the internal elements will be too short.
Using a 154MHz antenna on 146.745MHz will mean that the elements will
