I don't think that will touch the "coax" used to feed the 14.7 KHz VLF antennas at Cutler, Me or Jim Creek, WA, that I copied submerged in the Barents Sea. I recall photos of the "coax" and I think i
Work is close to completion on the ham shack at EI/W5GN, and I need suggestions on how to create a feed thru for the RF and Control Cables for the antennas and (eventually) tiltover tower. They will

Has anyone half-sized Cebik's 44 foot high by 149 foot long 40 Meter Bobtail Curtain in both dimensions for 20 meters? Did you use open feed to the tuner in the shack, or did you have to use an LC ne
Negotiate with your neighbors to use their 130 foot trees for your lowband wire 160 antennas, and agree NOT to sue if they fall down, in return. 73 Barry, W5GN _______________________________________
In 2003, I (actually, I watched, while Bill, N5YA, and a 60 ton crane with 161 foot boom did the work) installed a US Tower HDBX72 with a 24 foot mast, and mounted a 2-el Cal AV 40 at the bottom and
I had a BigIR vertical, including the 80 meter coil, but after three separate problems: the strip jammed inside the motor housing when I dissassembled and reassembled the motor drive shaft broke, so
I needed a 60 ton crane with a 160 foot boom to reach to the back yard to remove the old tower, and to install the replacement and antennas. A city permit was required (done by the crane company) to
The biggest advantage I found with my Serial #1 TH-7 was that its broadbandedness allowed coax feed without tripping the Alpha amplifier - previously, I had to go thru a matchbox to make the amp happ
The OB16-3 is 16 physical elements, 8 on 10, 4 on 15 and 20, si it is designed to be better than the Th7, and is also more expensive. It is also more broadband than the Th7. With the TH7, I was just
43-foot Zero Five SWR measurements at EI/W5GN It "towers" (to keep the posting on topic!) on edge of a 65 foot bluff on the Atlantic Original 8 radials: three x 65 foot radials three x 33 foot radial
A question from my Best Man, F/K9ORP: Can Ladder Line be run thru underground conduit under a road to feed antennas on a tower across the road, with no impact? By itself? Would a mix of coax and ladd
In the eary 70's in Illinois, we put a HyGain Vertical, the trapped vertical (maybe 18AVQ is the right number) on a 125 foot microwave relay tower with dual "flyswatters", those large 45 degree refle
I had pretty good success in the Stew Perry on 160 feeding my 43-foot Zero Five, adding a 90-foot wire from it's tip to the top of my 33 foot BigIR, with the "horizontal" wire more of a "U" than hori
"In short, I outperform most people on 30 and 40 with wire antennas. Whether the pile-up is in the Pacific, Africa, grayline to northern EU or LP to the middle-east...with 800 to 1000 watts I'm usual
I just posted my results with a Zero-Five 43 foot vertical, used as an Inverted-L for 160. As-is, the 43 footer will work 160, but only out to about 1000 or so miles with 100 watts, over land (to the
"I would love to motorize them but have never found motors I could use." Dick, W5ONL loaned me a fine remote tuning box; the motors were those very cheap 110AC motors used on outdoor charcoal-fired r
IF you city zoning permits antennas/towers at all, it will almost definitely have a setback distance from your property line, that will restrict where you can locate the tower base, and your antenna
To answer some of the postings and to close this thread: The "definitely" in my post was the setback to the tower base, IF there is an antenna ordinance in the first place. And, no argument that your
Since you brought it up, what is HFTa'S optimum slope angle and distance for maximum gain? I assume it's different for each HF band? Barry, W5GN _______________________________________________ ______
