If that's the problem, 3 dB ain't going to make the difference.
Looks to me the problem is the system receiver / not the
transmitter.

The problem is Not in the system Receiver

I think if you up the power and do get 39 more watts to the ant that
could make a verry

If you do that, then you are not working it properly, they may be able to hear the output just fine, but when you go back through the duplexer, then you get the loss of the duplexer and if possible any desence that might be present. Also, how far are you from Gary? This in itself could also be

Your Right Ken .. this could be all for nothing ..
but if you don't take the time to try you will not learn .. and maybe all
he needs is a couple of watts to just give them enough sig in the mill
for them to RX better ..
never know untill you play and learn ! .. and 220 is a fun band to
play
I suspect the shorter wavelength of 220 is able to be reflected and
refracted inside the building much more easily than does 2 meter energy. I
bet UHF would perform even better but there are too many variables to say
for certain.
For construction crews, 440-ish wavelengths are MUCH more
