It seems to me that in one of these V4k threads there was some reference to a 31.5' vertical, and less than  1/4 wave radials with a less than 1/4 wave circumference hoop on the radials optimizing the gain on horizon of the antenna; that is, if my memory serves me.

I have put the Qv4k back into the air. I needed to readjust the gamma for a match as I apparently bumped it out of adjustment moving the long-legged thing around. Owing to the fact that my homebrew version is likely not optimized to the extent that the commercial models would be, I am finding it inferior to my 5/8 GP.

I can hear farther out, and more clearly on the 5/8^ antenna. I seem to be equally well heard by each, but the increased white noise level on the Qv4k leaves me helpless on this antenna compared to the 5/8 wave. Admittedly, the more conventional 5/8 GP has become so familiar to me that I believe if I had sufficient materials around me i could have a working model up in the air and operational within two to three hours.

I am wondering if I should attempt to maximize the Qv4k by adjusting the vertical length, the hoop, and the radials to the best model discussed. If so, can someone remind me what those exact, or near exact dimensions are.


As it is now:


5/8^ GP  @ 10 miles to base station    9 S units

Qv4k       @ 10 miles to base station    7 S units


5/8^ GP  @ 20 miles to base station    5 S units

Qv4k       @ 20 miles to base station    3 S units


5/8^ GP   @ 30 miles to base station   2 S units  w/understandable audio

Qv4k         @30 miles to base station    0 S units  w/a mere whisper of sound 

 

5/8^ GP   @ 40 miles to base station    0 S units  w/understandable audio

Qv4k        @ 40 miles to base station    0 S units  w/nothing in the receive


At this point I can only fairly assess this as faulty craftsmanship  on the Qv4k.


Anyone have those other dimensions?
