Just like cars, never buy one built on a Monday, Tuesday after Monday Night Football or Friday or other days that follow holiday weekends < ;-) UR experience may vary! Have Fun, wa3gin ______________
Here is the PDF link: http://www.ncjweb.com/k3lcmaxgainradials.pdf Gary, you really need to read... _______________________________________________ _______________________________________________ Tow
What is missing for me on this article is at what take-off angle is the increased efficiency realized? I suspect the smaller radial systems raise the angle of radiation slightly or maybe not so sligh
The antenna is surrounded by a salt-marsh...I watched the impedance of the 1/4 vertical drop each time I added four 1/4wave radials till I got to 48 of them...then no more change. I left it at that a
One of our town's local 2m repeaters uses two separate antennas one for transmit and one for receive rather than spend the $1,500 for a duplexor. The penhouse concrete walls provide about 100db atten
Yes, unlike your micro wave the rebar is spaced at about 12" square, not a very effect shield at 2m. Not even HF. Must be something else??? _______________________________________________ ___________
Hi Folks, Some months ago I requested info regarding a replacement transformer for subject. I've gotten the summer honey do list down to a manageable list and should have time to replace the transfor
Hi Folks, I'm looking for several 1815 bulbs. Please respond direct. 73, dave wa3gin _______________________________________________ _______________________________________________ TowerTalk mailing
This thread is getting pretty tired....can we start talkinng about antennas again!? _______________________________________________ _______________________________________________ TowerTalk mailing l
Harris has a $500 minimum order requirement. Its no wonder the Tuning Unit sells to Uncle Sam for over $12,000. In search of a copy of the RF-2601 manual. 73, dave wa3gin ____________________________
Hi Folks, In search of a manual "EE060-GC-OMP-010/CU-2475A/U" for the RF-2601 tuning unit. Neither Harris nor US Printing office carry this manual. 73, Dave Wa3gin ___________________________________
Hi Folks, Looking for a commercial 80-10m for a building roof top install. The building roof is rubber so we're using non-penetrating roof mounts for the base of the vertical. The building owner pref
Hi Folks, Many years ago Motorola made a nice 100 watt 2-30MHz long wire auto-tuner. I found one in great condition but no no info as to how to wire it up. There are a few multi-pin connections on th
I remember some folks using springs like this in their rotor to mast connection ala Back Lash....maybe somewhere down the line the story was mis-understood and the coils migrated to guy cables -- sca
Where do they find this stuff. The GIN POLE pictured in this link was so big the riggers climbed it to set the new digital/analog TV antenna. Amazing photos...http://www.ustowerservices.com/projects_
...then again. If you already have a great radio perhaps the 3L and a used amp for $800 would get you another 6-10db. Hearing them is one thing...being heard is something else ;-) enjoy, dave wa3gin
Farmville, VA Irrigation tubing has some good people and reasonable prices. 73, Dave Wa3gin If you use the 4" irrigation tubing there is an option on the wall thickness. They sell what is called "tor
Why not just purchase two 5 or 8 port automatic antenna relays. Stick your LC network for each band in-between the ports. One coax input, five outputs to LC networks, five outputs from LC networks to
The high voltage appears at the tip of the vertical, where the corona ball goes. I believe the feedpoint is the high current portion of the antenna where most of the radiation starts... --Original Me
We did a test here with a vertical cage antenna. Started with four quarter wave radials. SWR was 1:1...every weekend we added four more radials. Each time the SWR went up and the input impedance went
