I have a measured different resonance curves and corresponding VSWR for my 80m dipole array depending on which antennas I select. For example, the antennas are oriented NE, SE, SW, and NW. I have two
using an Autek VSWR with the amplifier. I had antennas with measure the VSWR The power of the device has nothing at all to do with the SWR and mutual coupling. You must have other antennas or object
The destructions that came with my Comtek phasing box(s) suggest that each element be cut about 5% long, the array erected and then observe the frequency that the minimum amount of power is dumped in
Except the 0 degree port and the 180 degree port are actually connected in parallel (the 180 degree port is connected to the zero degree port through a phase reversal transformer/un-un). Thus, you h
frequency (0 ohms Why not Paul? Anything that changes the common mode impedance of the system can change the resonant frequency of an antenna system. As a matter of fact if the feedline is not match
Tom, I read from your comments that the Comtek box doesn't work and cannot work. Is my reading correct? sheesh, I just bought one, based on favorable comments read on the net.... 73 de Mike, YO3CTK -
and cannot work. No, I never said that. It's obviously a good system, many people use it and have been using it for years. My only point is people look at these systems and assume they can take the
Bringing up a question in the back of my mind... This is a pretty easy theoretical analysis. Does anyone have the component values in the Comtek box? (especially a rough idea of the parasitics and Q
