I have some rg-59 that I want to use for phasing a couple antennas in a low-power environment. The 2 cables are marked as: S.I.W TYPE RG-59/U-SP-95 MADE IN U.S.A and S.I.W TYPE RG-59/U-P-95 MADE IN U
Jim: I'm not that far away from thinking the same thing. However, I want to call the distributor tomorrow and see what they say. They're well known in the ham community with a pretty good reputation.
To add to Jim's comments, I also use the VNWA3 and wish that I had bought one years ago. The Yahoo group is a wealth of expertise. I'm currently building a set of OSL standards for UHF connectors. On
Take a look at the pvrc antenna mount. The biggest issue might be the square boom on the Optibeam. 73 charlie, k1xx _______________________________________________ ___________________________________
I've used both the 2 wire slide and tram methods. I found the tram method to be best. Read Ed's post. Strong agreement with Ed's comments. Another poster suggested using a tiller on the antenna's boo

Just a word of caution regarding the shipping of six-foot lengths of tubing from DX Engineering. Buried in the "fine print" on their web page is the following.... Oversize items: A special handling s
Neal: Check out the VNWA3E designed by DG8SAQ and sold thru sdr-kits.net in the UK. 73 charlie, k1xx I would like to hear some opinions on this device and others from my fellow TowerTalkers. Neal, K4
I have the HP triplexer/BPF set from VA6AM. If you're interested in my measured data, drop me a note. 73 charlie, k1xx Any reviews on 4O3A's triplexers/filters? KH7XS _______________________________
For those that don't know, rg-179 was used in the rf chokes that were part of the W1FV yccc 9 element circle arrays. I assembled well over 20 chokes to support the 3 current arrays at the pj4k. As a
I also recommend using the 4-hole flange connectors. No more problems with spinning connectors. I bought from 2 different ebay sources....try2best2011 and rfbat. I prefer the connectors from try2b
Measuring at 50 MHz, the difference in loss / 100 feet is about 0.4dB for the 2 cables. Make it a 1/4 section at 80 meters and you're near 0.1 dB difference in loss. Good luck making meaningful mea
Sorry Jim, but I have to disagree with you on the carrying cases. I find them very convenient. I just returned from another week on Bonaire and simply threw the cases and analyzer in my backpack fo
I need some help selecting some type of material to build some custom center insulators. I have what approaches zero experience in this area. The insulators will be used to support near vertical dip
So following up to last week's thread, a couple questions that will surely get some traffic... Do we really need common mode chokes on our transmitting antenna? The station is located on an island in
I opened a mystery box from the attic a few weeks ago and found a pair of in-line coax splices that I'd like to identify. Though I've reached out to a few folks, so far I've struck out. The only ide
Mike: Back in November I measured an old DLW filter. Unfortunately, I don't remember the specific numbers for BCB rejection. The filter is down on Bonaire and I won't have access again until my tri
Kurt: Sometime back in the summer of '21, I also checked out the Morgan site and it was somewhat the same as you saw. However, when I checked in the Oct/Nov time frame, they seemed to have cleaned i
Morning folks and Happy New Year to all. I am looking for equations, or an on-line calculator, for open-wire transmission line using different size wire. So far, I've struck out. Can anyone offer any
