Some months ago when it was being discussed I said I would check the price of the 500' spool of #14 insulated. I have previously bought them for somewhere between $12-$14. Others reported higher pric
Anyone have any knowledge, plans, web site for the Sabre model 600 log periodic? Just acquired part of one. I'm wondering what's missing, etc. 73 - Rich, KE3Q ________________________________________
The lower one will tend to be better (you will be louder) for closer in things and the higher one will tend to be better for farther away things. A low tribander, even lower than 65', can be very goo
Here's a thought: 1. Choose which of the three you like best. 2. Trade or sell the two others for one more like the one you like. 3. Stack those two antennas, one at 30' and the other at 60'. - 60' j
A few comparisons, for your interest, anecdotal stuff: 1. Telrex made a 4-el 20 on 36' boom. W4QAW (who I acquired one from) and others I've heard talk about this one say it worked well but the front
I think it depends on what the "extra" element is doing. If it's close to the DE as in WA3FET's OWA designs (used by K3LR and others), as I heard 'FET and 'LR note in the Dayton Antenna Forum talk on
And, you remember the first Yagis that had old wooden ladders as the boom! For most of us, myself included, we've only seen photos of them on QST covers and such, although I did acquire "most of" the
Right, as I recall from being at A61AJ and we had to go out and buy wire for Beverage antennas, in the rest of the world these things go by mm (millimeter) sizes, though I cannot remember what the eq
By the way, #14 actually means "14 gauge," and -- someone help me on this -- I think it means something like 14 spheres of that diameter would equal a certain weight. Somehow that doesn't sound quite
I would think the on-concrete mount would work but you'll have to guy the 4x4. Losing 4' of the height is not too big a deal for the theoretical performance gain or loss you will experience. Putting
Here's another thought... I personally agree with those who say you don't need a 4x4x4' hole filled with concrete to support your 4x4! I also think a pressure treated (Wolmanized) 4x4 should last as
I think a lot of us use steel angle rather than pipe, because then you don't need a plate to mate the two pieces of pipe. A steel angle 2-4' long, with a single "muffler clamp" (U-bolt with saddle, a
Sounds like a good idea that should work and also keeps it down to just one U-bolt and avoids having to acquire and drill a plate and use 4 U-bolts. Even a pressure-treated 2X2 (pine), which is what
I remember when this discussion came up some years back some professional concrete guys told us that the concrete, unless it was an extra wet mix, cured to 80-90% of its ultimate strength within 24-4
Yes, hi, Malcolm. The official name is United States Tower Services. I have always been able to find it by "Googling" that name and Frederick, Maryland. Also, they're on Agro Drive. 73 - Rich, KE3Q/W
My guess is you probably want to separate them quite a large distance since they both cover 14 MHz, probably a distance similar to what you would stack two identical beams to use them as an array --
80% is the "standard." There is nothing magic about that distance. Actually, farther away guying is better structurally, but there is a point of diminishing returns. It is possible to guy closer, as
It's not our place to "decide." We should all stay out of it. I think it was inappropriate for Cariello to bring this before us, taking advantage of Steve's largesse in hosting this reflector; it was
Anyone have an idea (or facts) how high I could go unguyed with Rohn 65, assuming a single 48' boom monobander for 20, or 15, or 10 (plus appropriate rotator, and I'll have the yagi right above the t
Okay, it looks, then, as if Rohn 65 would do the job at 50' but wouldn't be enough at 60' -- unguyed. I would guess that Rohn 80 would have a little more capability, being huskier. Even putting one g
