1. [TowerTalk] RE: [CQ-Contest] Testing Stubs (score: 1)
Author: dick.green@valley.net (Dick Green)
Date: Sun Aug 3 21:16:21 2003
Mike, I agree that double-shielded coax might help (in fact, I should do that in my shack!) I've found that stubs and filters don't always make a big difference in the S-meter reading at the harmonic

Bob, The impedance of the coax used to make the stub won't affect the results as long as the stub is cut to the correct length for the velocity factor -- i.e., the correct electrical length. Since th

Cushcraft packs little tubes of silicone grease with their coax booties. It's never been clear to me exactly where it should be applied. Seems to me that if applied to the threads it would interfere

Thanks for re-posting this important information, Jim. I've been putting together a climbing system based on these principals, but with a couple of variations made possible by the harness I have. I b

John, I don't know if I can help, but I'll tell you what I did. I laid 265 feet of 1/0 stranded bare copper wire at the bottom of a 4-foot deep conduit trench and used it to connect the tower ground

Date: Sat Jul 19 01:15:00 2003
In my search for SS u-bolts to rebuild a 40-2CD, I found that Cushcraft has a good selection and the prices aren't all that different from other sources. 73, Dick WC1M

I put down 240 radials for a 4-square on a piece of densly forested land that had been cleared for the purpose. There were lots of roots, stumps and debris. I used bare #16 copper wire. For staples,

Forgive me if this has been asked a million times before, but I need a source for stainless u-bolts. I'm rebuilding a 40-2CD and need u-bolts in these sizes: 2 1/2", 2 1/8", 2" and 1 5/8". 73, Dick W

Thanks to all who responded on this. A lot of searching on the web leads me to conclude that stainless u-bolt sizes do not come in 1/8" width increments, only 1/4" increments. However, I have found s

Depending on the design of your phasing network, the per-element VSWR will not go down when the elements are phased. What happens with hybrid couplers like Comtek's is that the reflected power is dum

I agree that the efficacy of screw in anchors depends on soil characteristics, and that a high-rain area is probably not the place to use them, but I'd say overloading the tower had something to do w

Pete, I've had all sorts of trouble with critters chewing cables and coax. They really seem to like LMR400UF, but not 9913 and Buryflex as much. So far, I haven't found a rotor cable they don't like.

Oh! That reminds me of something I'd almost forgotten: about six or seven years ago I had my 1993 Audi 90 Quattro car in for service and they told me mice had eaten through most of the engine wiring.

I also own three AB-577's and have had exactly the same experience as Dan. If the wind isn't blowing over 5-10 MPH, you can do the whole job yourself, as Dan describes. If the wind is blowing harder,

I should mention that the AB-577 has a big brother: the AB-621/G. I've seen the manual. The design is very similar, but the 621 is a lot beefier and weighs more -- it would take 3-4 people to haul it

Paul, You might get away with CW and SSB at higher power levels, but do not go key-down at anything over 500w. In my case, the coax melted inside the antenna. It was quite a bit of work to replace it
