Ok you antenna gurus, I have a funny problem. Whenever I try to reach a
certain repeater on 2 meters, (146.700-), I can't do it. The repeater is
about 25 miles from here. I have an outside antenna with 6 db of gain
similar to a Diamond, a new coax and 50 watts of power. The base of the
antenna is about 15 feet fron the ground and the repeater doesn't need a
tone. What's funny is that I can reach repeaters that are a lot farther than
this one but not on the the same bearing. A friend of mine who lives about 3
miles from here has no problem whatsoever in reaching the same repeater.
Some hams who live farther from the repeater than me can use it with no
problem. The only difference I can spot is that there are a few houses
around mine that are 4 stories high while mine is a bungalow. Could this be
the reason or am I missing something here? Thanks for any help.

VE2CJW, Mike.
