How far should my hf antenna be from me

WebMy 6m/VHF/UHF triband vertical is 8ft diagonally forward from my TV antenna, at the same height and is slightly to the left of where the TV antenna points. Causes no problems. The HF antennas should cause no problem. Usually if there's a problem its because of a crap signal being put out of the ham transceiver usually from overdriving the audio ... WebOdd as it may seem, attics have a certain capacity characteristic (attic wiring and HVAC ducting) and antenna wires should be no closer than 10-15 feet from any roof top, even if it's a nonconductive roof material. Antenna wires should be at least 20 feet from other similar frequency HF antennas, even verticals.
