Get yourself a GMRS license and put up a small 462.5 75 to 462.725 repeater
and all of your family could use it.

Ryan,
A few suggestions:
Antenna discussion is not Off Topic for this list. Folks that filter
their messages withing their email clients will not see your post,
however they will see this reply as I changed the subject line. A
commercial antenna will last 20+ years as far as the radome is
Hi Ryan
Kevin is on the money, with antenna discussions connected with repeaters
very welcome to be sure.
A couple of suggestions before anything else is tried. If you want to see
if you have a broken antenna solder joint you can test the antenna easily,
especially since you have such a short

From a user standpoint, in my opinion, there would be little noticeable
difference. However, the VSWR is really a lot higher that what the meter is
reading due to the losses.

He's in Brazil. I don't think they have GMRS there.

Hi Ryan
One other point. You stated that you changed feedline
An idea is to use a simple repeater controller connected to the radios'
speaker-mic connections.
one radio will receive only, one radio will transmit only. Make sure you
keep them separated about nine feet or greater if you are going to use
the amp on the one that is going to transmit.
Dave,
The output power of a repeater has relatively little effect on its coverage;
it's how well it receives that is important. A 3dB reduction in the
repeater's received signal strength can be significant, especially if most
of the users are just above the noise level when the antenna system is
I agree with Dave, a 3 dB change may be noticeable, but not to the
degree Glenn states.

I think we need to look at the original context posted:

can't key up the Rpt with 50 watts in a 30 mile radius. We Have SWR of

Thanks for your reply. Correct me if I am wrong, but in order to make the audio sound

Brian,
There are many R-100 owners who have discussed similar issues on the
Repeater-Builder list, and may be able to help you. Also, the complete
R-100 service manual- among other documents- is available for download from
the Repeater-Builder Technical Information Pages (RBTIP).

John,
That (GMRS License) would be a bit difficult for Mattos – he’s in Brazil…
