1. Topband: rig question (score: 1): Author: Telegrapher9 at aol.com (Telegrapher9@aol.com); Date: Sun Jan 26 15:18:17 2003; I recently acquired some new equipment and haven't done a comparison yet. I have been using a Kenwood TS-570SG for some time and the CW DSP does a great job of pulling signals out of the noise. Now I; /archives//html/Topband/2003-01/msg00219.html (6,445 bytes)

I was thinking that one of the small cables (RG178 or RG179, note that these are not double shielded) would do the job and not be so heavy and cumbersome.

I haven't seen these articles but I will be on the look out for them. Twin lead will certainly have lower loss and is cheaper than coax. Although the loss of small coax is high, this; /archives//html/Topband/2002-12/msg00054.html (7,363 bytes)

I last downloaded it two months ago. I also have not been able to find a valid email address for Brian Beezley, K6STI. Here is a link; /archives//html/Topband/2002-12/msg00091.html (7,472 bytes)
7. Topband: vert performance and improvements (score: 1): Author: Telegrapher9@aol.com (Telegrapher9@aol.com); Date: Sun, 8 Dec 2002 13:49:42 EST; My 38 ft top-loaded vertical is finished and I made 173 QSOs in the ARRL 'test running 5 W. Rad EFF is 25% and the effective GND loss is 20 ohms. The next step is to try a "base-hat" in place of the; /archives//html/Topband/2002-12/msg00114.html (6,811 bytes)

The QRN level here was S-3 during the ARRL 160 M and S-9 during the SP.

I'll run some simulations with nearby Beverages open and then terminated to see what is best. I bet it's best to te; /archives//html/Topband/2002-11/msg00178.html (7,365 bytes)
12. Topband: beverage impedance (score: 1): Author: Telegrapher9@aol.com; Date: Tue, 23 Dec 2003 09:35:33 EST; I've been working on some methods to determine proper Beverage termination.

A quarter wavelength inverted-L would be great on 160 meters. The radiation resistance is 22 ohms and the pattern is omnidirec; /archives//html/Topband/2006-11/msg00052.html (7,423 bytes)

The 65' tall Inverted-L has a radiation resistance of 18 ohms. Depending; /archives//html/Topband/2006-11/msg00130.html (8,039 bytes)
