Daniel, I built solid 40m verticals with relatively inexpensive aluminum tubing from Texas Towers. I started at 2.125" at the bottom and I think they telescoped to 1.25" at the top. There was 1 guy l
Peter, extending out from the 40m verticals themselves. Others here can probably offer a better technical explanation as to why, but I'd say its because with 1/4-wave verticals the electric field nea
Phil: if it was a mistake for the seller to send the goods before receiving payment, it would be an equal mistake for the buyer to send payment before receiving the goods. Outside of meeting in perso
If he's talking about full-size 80m verticals, I would assume they would be guyed in which case 1 foot into the ground would be plenty in any wind as in this case the its only job is to carry the ver
Maybe it is QTH-dependant and I don't know what the models say, but in A/B tests I've found ground-mounted verticals with 120 1/2-wave radials perform significantly better than elevated verticals wit
Tom - the UV jacket (such as that on Phillystran) supposedly tastes like soybean to the squirrels. Once they get a taste for it they keep coming back. I've never had a problem with polyester though,
My concern wouldn't be for the operation of the antenna, but what might happen if I attempted to work on it with the nest there. I've disturbed a nest and had them come after me and it wasn't much f
The SteppIR's elements have an interesting solution. They have pieces of round foam stuck in the ends of the elements. They are supposed to let any water out whilst keeping the critters out. The boo
I'm not an insurance agent, but I've had it explained to me by a few along the way and thats never how I interpreted it. And, I know people who have made claims and thats not how it worked. Replaceme
Although I'm primarily a CW-only op, I think its kinda good. I sure wouldn't want someone telling me I have to become proficient in SSTV or PSK31 or any of those other modes I don't care about in ord
I inadvertently wired my garage door opener into a GFI breaker. Every so often when running at full legal limit it would trip. It didn't happen a lot; perhaps once a month or so. I took the door open
I've never had to shoot birds off an antenna, but if I had to I would invite my neighbor over and have him do the same thing he does when the woodpeckers go after his log cabin. The first shot goes
My local Lowe's stopped selling #16 insulated wire less than a year ago. The smallest they carry now is #14. But, when they did have it, it was $20 per 500 foot roll. There is an electric supply stor
$16 for a 500' roll of #16 stranded works out to 0.032/foot. There doesn't seem to be a huge difference in price. But, I'm curious if you or anyone else have any long-term reports on using such wire.
Since the original question was posted by a VK station, it might be worth noting that using Polaris to locate north can only be done in the northern hemisphere. It is not visible below the equator. D
In addition to the link N4ZR pointed out, check the help file that installs with HFTA from the antenna book's cd-rom. I found it to be a lot more instructional than what is explained in the antenna b
20 miles is ~32km not 12km. That enough wire for 420 1/2-wave radials. Wow. 73, Tom, NI1N _______________________________________________ See: http://www.mscomputer.com for "Self Supporting Towers",
As N8AU pointed out, you wouldn't need the coil on the Butternut if you were only using it for the higher bands. But, it needs it on the lower bands (80m in particular) where the feedpoint of a short
Jim - I have a similar setup. I have a 4 element SteppIR and OptiBeam OB2-40 on the same mast. They are 10' apart (40m on top) with the booms parallel and I've not had any interference problems. 73,
I ordered my 4el SteppIR at Dayton in 2004. Their "show special" was an extra year on the warranty. No price breaks though. 73, Tom, NI1N _______________________________________________ _____________
