Re: [TenTec] Apartment antenna help (score: 1): Author: joel hallas <jrhallas@optonline.net>; Date: Mon, 27 Mar 2006 11:26:51 -0500; Al, I expect that what you propose would work, but suggest that it would work even better wit a wire at least a quarter wavelength or longer at the lowest frequency, and longer will work even better.; /archives//html/TenTec/2006-03/msg01205.html (11,963 bytes)

(score: 1): Author: joel hallas <jrhallas@optonline.net>; Date: Wed, 01 Feb 2006 20:54:23 -0500; Bill, It sounds like a good system and I expect it will work well on all bands at which the loop is a full wave or longer. That being said, at the full wave band, it will be mostly a NVIS antenna, wi; /archives//html/TenTec/2006-02/msg00034.html (9,581 bytes)

Re: [TenTec] openwire feed OT (score: 1): Author: joel hallas <jrhallas@optonline.net>; Date: Thu, 02 Feb 2006 14:37:48 -0500; If you use the coax as coax, all the fields are within the coax so relative spacing between them doesn't matter. I tied the shields together on both ends of the run so the signal will divide properly; /archives//html/TenTec/2006-02/msg00060.html (12,807 bytes)

OTOH, the intent of the QST review is to balance it with subjective assessment of how it "feels" to run the radio. Great numbers are fine, but t; /archives//html/TenTec/2006-02/msg00995.html (8,606 bytes)

An HF over-the-horizon (OTH) radar guy would call it "backscatter" and that is exactly what the Russian (or I should say Soviet, I guess) "woodpecker" HF signals of the 70s and 8; /archives//html/TenTec/2006-01/msg00050.html (11,894 bytes)

One other thought would be that a test into a good, solidly connected, dummy load should eliminate RF as an issue and verify proper operation under even more ideal condit; /archives//html/TenTec/2006-01/msg00326.html (11,567 bytes)
