Thank you Kevin for restoring the list.
We are looking for a good 800 MHz repeater antenna that can handle up to 30
or 40 watts.
Any recommendations ?

What Sinclair antenna would be a match to the db420? Anyone know a
ball park figure on pricing? Any dealer suggestions to deal with?
The suggestion in earlier post mentioned that Sinclair might custom
cut a vhf / uhf style antenna...something like what the db314 is.
Curious also if anyone has
Does anyone have any suggestions for some companies that would do work
on the southside of ATL? I have a few in mind myself, but we are
getting names so as to get bids together.

Contact Sinclair, Comprod, TX/RX Systems or Telewave directly. They all sell
direct to hams, I believe. All can provide what you desire. All will be
expensive.

You can peruse the Sinclair catalog at www.sinctech.com
It is a Canadian company, so shipping to Stateside addresses is one factor
to consider. I bought two SRL-222 VHF dipole antennas for 2m use, several

I'd say the chances are very good that you can switch power supplies.
Nevertheless, please advise the model numbers of the power supplies you

Keep in mind that the single channel radios (like the M-10) are not that common.
Just use any GM300 / Maxtrac / Radius model and only program one channel.

Very true John, but the question was asked about if it could
be done. Yes it can and I have done it... with mixed results

That's only true for 1/4 wave verticals. A 45 degree droop brings the feedpoint
Z up to 50 ohms (from a nominal 35 ohms).
But, for 1/2 wave verticals (which is what this one is), the radials need to be
perdendicular to the radiator for the feedpoint Z to be 50 ohms.
