Yes it has been a few years since I dabbled in the wonderful world of radio so please keep that in mind. I am just starting, from scratch, to throw together another station. Today I put up my dipole antenna for 2m and have already hit a snag. The swr is high and I can't get it down. It is on a boom which runs 90 degrees from the tower at about 20 feet. I would say it is in the vicinity of 15" from the tower. My thought for the high swr is that it must be too close to the tower. I hate to ask for help on such a simple thing but I haven't got any reference material left to jog my memory. Any ideas?

First of all is there any way to see where your antenna is resonate.This is a starting point.If your vswr is low at the lower portion of the band Shorten it.If your lower at the upper portion start over.Start with 1.60 ft on each side.Also could be shorted out.Make sure the center of your antenna to each leg is not shoeted out to each side.
