I will take the bet! I never had wire fail in Quad from flexing. There is (almost) no flexing when antenna is properly strung, with just enough tension to keep the wires from flopping or flexing. In

Transmission line baluns are poor baluns for most applications. They are much more impedance and load critical than choke baluns, more lossy, and don't do as good a job. They are more difficult to m

Actually, the parasitic systems work fine with 4 or even three dipoles, although the beamwidth increases proportionately. Wx0B and I are arguing offline about which system shows better F/B and gain

<< I highly recommend Davis RF Buryflex. It is 213 and is direct burial. There are two rules of thumb: one: one foot which is the depth that a shovel can accidentally cut through it; and two: 18 inch
ERIC: The main problem here is when you rotate the boom for vertical polarization the mast will be exicted with RFand upset the vertical pattern and F/B. You have to mount the entire beam on one side
Coax under ground has many enemies from all the comments I've read on TT. Cable TV runs their coax on messenger cables mostly out of necessity. That's equivalent to going up the tower and to the beam

Jim that is a very good question and that will be answered also. This is the 51st e- mail today I've sent. Typical spacings are 4-6" which gives a range of about 400-600 ohms Zo depending on the wire
am I right in thinking that the general answer would be to make the 75-ohm feedline a multiple of a half-wavelength at the lowest operating frequency, and that the worst situation would be if the 75
