Re: [Elecraft] OT:. G5RV's

The tuner loss also depends on how it is adjusted. For example the very popular high-pass Tee with three adjustable elements has an infinite number of possible combinations that will effect a match on the same load Z. One of them is the lowest loss solution, all of the others aren't. As I

Re: [Elecraft] OT:. G5RV's

I guess a little discussion of semantics is in order. Yes, EZNEC shows for example, that a 12 AWG wire, 102' long and say 50' above avg ground shows an impedance of ~98 +j0 at 14.32 MHz, so it is resonant in the 20-meter band, because the reactance is zero, and it could be called a "resonant

Re: [Elecraft] OT:. G5RV's

I know handbook descriptions have declared this for years. They're simply wrong. The folded part is a transmission line, it doesn't radiate and it has an impedance different from the antenna. Why not just add a hundred feet or so of transmission line to a 10' dipole and call it a 160

Re: [Elecraft] OT:. 42 ft Vertical

42 feet is 5/8 wavelength on 20 meters. That is the longest vertical one can use before the radiation angle starts to rise above the horizon. Since operation on the lower bands (esp. 80 meters) wants the longest possible radiator, 42 feet is an excellent compromise for 80-20 operation (with proper

Re: [Elecraft] Trying wspr again with signalink and K3

I would suggest that the WSPR audio is not reliably triggering the SignaLink PTT. The SignaLink uses the incoming audio to trigger the PTT. In other words, it is a VOX function inside the SignaLink box. You will have better success using the K3 VOX than trying to use the SignaLink vox (to

Re: [Elecraft] OT:. G5RV's

Bill, That is correct, but the currents on the 33 feet feedline should be balanced and of opposite polarity - so they cancel. The current at the radiator center will be less than that of a full size 80 meter radiator, so it will be less efficient than a full size 80 meter dipole with the

Re: [Elecraft] Trying wspr again with signalink and K3

I use VOX for all digital modes. I started with a SignaLink, moved to a Tascam unit, and now I am using the KIO3B upgrade to the K3 to give it a USB port. VOX will work fine with any digital mode that does not vary the sound volume as a modulation technique. (I think all the common ones use

Jim and all: Interesting comments on the G5RV (I've never built one but have a local friend that uses one). For years I used wire dipoles on HF bands: I made a 80/40m trap dipole, 80/40m dipole with removable clip at 40m length which we call the "Iditarod Special" as it was simple to use at

John, I think this is a reasonable conclusion. Early on I used a G5RV and it was invaluable reference for my later antenna building experience. I went to build doublets in the same space and I still keep an 80m doublet in the air. Recently I have gotten into building no compromise rotatable

When Varney created his G5RV in 1946 a great many Hams still operated on but one Ham band and parallel (open wire) transmission lines were still common. The 102-foot G5RV is a 1-1/2 wave center fed doublet at 14.15 MHz. According to one of my favorite wire antenna writers, (John Heys, G3BDQ

Wes.. Over the years, immediately after a change in QTH, I have used the G5RV as an interim antenna. My personal experience is that it is a reasonable performer, as compared to a single band, resonant half-wave dipole, at the same height, fed by the same coax/length. While I certainly
