I have a full size 80 meter dipole at 60' in the center fed with 300 ohm window line to a good tuner with the balanced input.  I cannot use it on 80 or 40 meters even at levels of 25 watts or more because of interfearance to my entertainment center despite snap on chokes on all input leads and every speaker lead and a high end ac line filter.  Therefore if I want to operate any frequency below 14mhz I feel I must try a vertical in a side yard located outside the shack.  The area is about 25X40 feet.  Radials can be put down in that area  There is a 50' tower with a triband beam in one corner of that area.  No other metal is in that area.  The feedline length to the shack is about 20'.  There is no height restriction in this area.  I only need the antenna for 75 and 40.  There is a 6' tall wood privacy fence around this area.  I would hope that using a vertical in this area would fix the rfi problem since the antenna would be a good 40' away from the entertainmant center whereas the center of the dipole is directly above it.  Suggestions please.  WB5OXQ
