I have made the purchase of an AB-621/G mast from a surplus supplier. The unit should arrive next week. I haven't seen it up close yet, so I'm wondering how much I'll need to disassemble it in order
Thanks, I should have mentioned, I do have a small tractor and welded up a fork lift for it this summer. I suppose I could put straps around the base section and pull if off the ground with the fork
Hi Frank, I believe I have that rotor on my mini-tower for hex beam. I used 2" square steel pipe and welded two plates into the center of the tower to hold the pipe. The rotor clamped on to the top o
Hi All, Does anyone have any experience with the spiderbeams? I would really like to put up something light-weight for 40 meters. I believe the spiderbeam 40m unit is only 17 pounds. Not sure if anyo
Yes, the Hex appears to perhaps be the easiest due to the shorter lengths needed. I would guess that for 40m the spreaders would each be no more than 29 feet long. I believe Max-Gain sells their "typ
Cable Experts has it in Both RG142 and RG316/U http://www.cablexperts.com/cfdocs/cat.cfm?ItemGroup=5&itmsub=0&bskt=0&c=0 Looks like nice stuff! :-] -- Bw_dw@fastmail.net _____________________________
I'm pretty sure RG142 or RG303 are both used for toroid baluns. If I remember they are spec'd out by the W2DU choke balun. 12 turns wrapped pretty tight around an FT-240-61. -- Bw_dw@fastmail.net ___
Hi all, I think I have the space to do this, although the property is heavily wooded with oak trees. I've modeled a V-beam with 219 feet legs for 40 meters. Eznec is showing a gain of about 10dbi. I'
WOW!!! Thanks Mike.....that does sound nice! :-] In my case, it will be 1.5 wl-long for 40m. I think its a great thing to try just for kicks. I use an arborist sling-shot and a tennis ball, filled wi
Hi John, You can check out these web-sites: http://www.w8ji.com/rhombic_antennas.htm http://www.vk5sw.com/Vee%20Beam.htm In my case it will be ultra simple. I will pull a line up into a tall tree for
Hi Rik, Years ago, I had a box outside with a electromagnetically actuated stepper switch made by Ledex. A rotary step relay. It physically turned a 4-bank double-pole wafer switch network, 9 positio
Thanks Ken, I didn't realize the aluminum stuff would stretch. They have it at lowes for electric fence wire, so I was assuming the stretching would be pretty much identical to steel wire. I can use
Thanks Paul! Do you know if 4Nec2 files be imported into Eznec? -- Bw_dw@fastmail.net _______________________________________________ _______________________________________________ TowerTalk mailing
I'm wondering what it would be like to live and ham close to Scottsdale AZ And wondering what property would be like there for a ham interested in having his own antenna farm? Wondering about propert
My only experience with the use of steel electric fence wire and the resilience of connections is using them as radials for vertical antenna experiments. In that case, I wrapped 8 wires together and
Hi Dick, It sounds like you want to add some directivity. Have you considered the Qaugi directive type antenna model? I seem to remember at least one ham who setup a lot of wire directionals. And one
You might check out the inverted V dipole. It may not have the sharp nulls at the ends that the standard flat dipole configuration has. http://www.seed-solutions.com/gregordy/Amateur%20Radio/Experime
I wonder what a used EF 240 would sell for?? Duane - N1BBR -- Bw_dw@fastmail.net _______________________________________________ _______________________________________________ TowerTalk mailing list
I had the same problem when I fired up a 500 watt amp on a certain band with a wire antenna. I added 3 FT-240-43 Toroids stacked together at the location where the coax feeds an external tuner locate
I have a 30 foot mini tower with a hex-beam on it. My property is pretty much all solid ledge which is exposed or covered by a few feet of dirt. For the base of the mini-tower, I drilled down a coupl
