Hi Guys, ALE stands for Automatic Link Establishment. It is designed to simplify use of HF radio for military personnel. Each radio has unique address, and...
Tnx Tino, To be honest, I had no idea what ALE stands for (and yes, I should have googled it.) If it is indeed only used for NVIS, well, we’re off to a bad...
I presume you are a military radio operator, so likely not a licensed amateur radio operator. Having familiarity with both ALE and frequency hopping used by...
Randy, Thank you for your reply. I am both a military operator and an amateur operator. KV9WMD. I am actually using the Micom 2 or 3 radios (100 watts) as the...
Rick, Thank you and, sorry about not signing. The following are the approximate frequencies. 13.4 - 13.6 14.6 - 14.9 17.4 - 17.5 19.05 - 19.25 22.9 - 23.0 25.5...
John, OK now I can comment on it. As you know, the military typically uses log periodic antennas because they have forward gain over a broad frequency range,...
A mil spec Spider for field operations strikes me as a great idea. Portable, easy to set up and take down, and naturally stealthy! You could call it the...
Brenton, What color would you like it? ;=) Shall we call it SpiderMite ? 73 Rick From: spiderbeam@yahoogroups.com [mailto:spiderbeam@yahoogroups.com] On Behalf...
If it had been an option, I'd have gone for the olive drab spreaders, wire, and SpiderMast . . . not that the neighbors would be fooled into thinking it's just...
I think the question specifically mentioned capacitive hat and Alpha Delta sloper, which is why I answered as I did. I have both in operation today and they...

Hi Fred, I am in Zone 1, rated at 130 miles per hour by FEMA. We have windstorms several times every year that exceed 100 mph. Wind related failures for me...

Thank you, Randy! I might think the hub to be the greatest stress point, and since you don't mention it, I guess it is holding up! Will the hub accommodate my...
YES, the hub can take masts up to 60mm (2.36"). Glad to see you were able to post again, Fred. 73 Rick, DJ0IP From: spiderbeam@yahoogroups.com...

You can add a 40m dipole to a Spiderbeam, rotated 90 degrees to the other elements. It uses the 20m director and reflector as capacity hats. This is not a...

My tower is a free standing 50 foot alumna tower. The rotor is mounted on a platform inside the tower The mast is HEAVY aluminum, 8 feet long. Five feet of it...
Fred, It sounds like quite the gymnastic routine to use the current mast to build the Spider beam onto. I would suggest using it as a gin pole, and getting...

(TNX response) Hmmm. Standpipe ... Didn't know they offered that. What would work is something like that 45 mm standpipe, but which was 2 inches, (52 mm)...

Hi Fred, I have a friend with an Aluma Tower, it is 60 feet, collapses down then leans over. We put his conventional beam antenna on from the ground using a...

QSL, tnx thoughts, Randy. I now understand that the antenna can be built upon its own short stand-pipe, so to speak, and it so happens that I believe I have...
Fred, How about tilting your tower over and supporting its top on a 6' step ladder. If you move the ladder in little, you can raise the tower such that its end...

Hi Fred, With a tower that light you will have no problem putting the HD Spiderbeam up with just a small amount of help from a second set of hands. One of the...
Last summer when I was tuning my spider beam, I found that changing the lengths of the adjustable wire stub sections of the driven elements did nothing at all...
