[Antennas] Question on open wire feeders and RFI/TVI

2003年4月22日 15:12:39 -0400

I Vote with the other comments (Peter-N9QZD and Robert-W9DMK). Whether
fed with co-ax or open-wire line has no effect on RFI/TVI. Its a matter
of antenna location relative to the equipment or antenna that could be
interfered with (how much RF field it is being subject to). 
It might be interesting to note, however, that antennas erected close to
large metal objects that may have poor electrical contact between their
parts (such as sheet-metal roofs, fire escapes, etc.) can cause harmonic
generation and therefore terrible RFI/TVI problems.
