I have a W6HIQ mobile antenna, the 4 inch, 160 meter version. Because of tooling limitations, the coil is limited to something like 12 inches. With the wire size W6HIQ chose, there isn't quite enoug
I found that a four element vertical array had essentially identical performance to my 560 ft beverage on 80 and 160. I have two of the DX Engineering ARAH-1 active receive antennas for sale. They ca
Moving the balun to the input does not affect core loss or balance. It does however change the operating conditions for *differential* mode current. If the balun is made of 50 ohm coax + ferrite, th
FWIW: We just paid $5K for a 6 foot diameter 9 foot deep drilled pier base. That's a turnkey price, including concrete, rebar, anchor bolts, grouting, and setting tower on the base. A few years ago w
I bought my tower from W6BH. They replaced all the crankups at the Table Mountain remote site for this reason. They needed to be cranked down in case of a wind storm, but it was not possible to drive
You would need at least a coax and rotor cable to go through this joint. My long range plan is to have a stack, requiring multiple coax and rotor cables. This would be quite non trivial to build a r
I just put up an inverted vee that is cut for 80 CW. I have a 250 pF series capacitor on the coax side of the balun. A set of normally open relay contacts are across this capacitor. When energized, t
Oh that's easy: 'cuz UST sez replace 'em every 3 years :-) (even though they supply zero documentation on the cables). I was supposed to replace mine in 1987. I'll get around to it one of these days
CB whips have a LOT of sag when used horizontally. They will work but aluminum tubing makes a lot more sense. Rick N6RK _______________________________________________ See: http://www.mscomputer.com
It's not that simple. Merely being able to lock the *frequencies* together does nothing to address phase. You will get random phases that change every time you tune the frequency synthesizers in the
Some of us have 100,000 feet of radials. Scrounging is essential at that level for most of us. Rick N6RK _______________________________________________ See: http://www.mscomputer.com for "Self Supp
My 160 meter vertical with 20 miles (12 km) of radials is indistinguishable on receive (except for absolute level of signal and noise) from a 30 foot vertical with four 30 foot radials. OTOH, a 40 m
I'm not surprised. The price of the tracks was astronomical, not to mention the price of the Hazer itself. By the time you got done, you could have bought a crank up tower. It would be interesting t
Speaking for myself; I want to do antenna experiments and don't want to climb to make each change. Also, it is useful to be able to change the height of the antenna as another variable in the experi
You can create a lumped element delay line consisting of a pi network with electrical phase shift of +X degrees if you use shunt capacitors having a reactance of Zo*Cotangent(X/2) and a series induc
I had an LB quad but replaced it with a 2 element SteppIR. The quad had replaced a KT34, for the reason that it added 17 and 12 meters. I never would have gotten the quad in the first place if the St
SteppIR is also a small business, yet it's only problem is that the volume of sales is so high they have trouble making enough antennas, and the price is actually fairly high (expensive but worth it)
I have A/B'ed 80 meter dipoles at 115 feet high vs 60 feet high. The high one is ~10 dB better on DX and the low one is ~10 dB better on locals (up to 150 miles or so). A really low one (at 30 ft) wa
Antenna guying is what is known as "corner case" in terms of application: 1. Because of wind loading, you need high strength vs diameter. All the "miracle" ropes I've seen are only high strength per
I didn't see in the report details of what the arrays were other than # of elements, but the 3rd paragraph says it all: "doesn't necessarily apply to superdirective arrays". There are enormous differ
