Hello, I was wondering if anyone has had any experience with a Twin Lead Marconi using 300 twin lead as described in Bill Orr's "Wire Antennas" book. For the low end of 160 meters, it uses a twin lea

Big snip... Tom, W8JI commented on that antenna in a prior post. http://lists.contesting.com/archives//html/Topband/2005-07/msg00015.html I seem to also remember another post where someone (Tom perha

If you can hoist a wire (or that twinlead) to the height you've described, the best way to utilize it is as a top-loaded vertical Tee. Simply tie both sides of that feedline together at the ground an

EZNEC says the antenna you described, over a good radial system, should be resonant at about 2.0 MHz with a feedpoint impedance of about 163 ohms (with some variations depending on wire used). The f

I have a similar antenna. Mine is about 75 foot vertical wire with a 75 foot topwire, over a field of 60 radials that vary from 50 feet to 130 feet on a steep slope. My feedpoint Z measured 25 + j0 a

Steve said, Is the UNUN approach better or worse or about the same as the reactive antenna with series capacitor approach? I think the answer to your question depends entirely on the quality of your

I would like to thank all who responded to my post. Your comments are most helpful. I have been studying ON4UN's Low-Band DXing book and in particular, the section on vertical antennas, ground planes

Nine (9) is in fact an odd number. But those wires are not actually radials. The WWV antennas are half-wave verticals, that is dipoles, not monopoles. The bottom half of each antenna is constructed t
