I'd like to piggyback on this question. I also have been searching for some time to no avail for this Cablewave Systems heliax cable: This is on a taped-on label - C371-21-27 1 16733 8L Serial # 0029
I have just the insulators for $2 each (plus ship), with at least 100 in stock... -Doug W6DSR A few months ago I posted that I had cured OWA Yagi VSWR rotational issues by isolating the big grip pref
I went to the effort to put all my radio equipment in a 40' shipping container where I used aluminum diamond plate on the marine plywood floor not to keep EMI from getting in , but to keep all the sw
I have 5 GHz commercial backhaul equipment on my property, with the 48 VDC power feed as described by K8LX. The major noise pollution is from the switching supplies in the backs of the antennas thems
The tapered line concept is actually simple and logical. My LPDA antenna uses one which I pulled apart to inspect when I was constructing it. The outside diameter of the coax stays constant, in my ca
I possibly have one of those. If the chain is #80 rather than 50 or 60, and if the rotor assembly is 878170-1, part of 877607-1, then I have info on it; however it sounds like yours might be a smalle
The RF current your receiver responds to flows on the inside of the outer shield of the coax transmission line, so what difference does it make what currents may be flowing on the outside of the shie
I have a lot of 1/4" steel core, coated guy line I'll never use. Take a gander at my website, on the Miscellaneous page at the bottom. Here is the link: http://w6dsr.com/misc/index.html -W6DSR ______
I have a Cablewave factory made 7/8" coax cable I want to shorten. The label on the cable is C371-21-27 1 16733-8L.1003-00 4-100. The male N-connector I have disassembled from one end. It has P/N 734
Well, okay, if I have to start from scratch, I'm looking at Commscope's HJ5-50 7/8" heliax or something equivalent. Since I'll be ordering a custom setup, I might as well upgrade to 7/16 DIN connecto
Air because the antenna's 1 5/8 EIA transmission line is pressurized. I already have the nitrogen setup for that outdoors at the antenna's base, but I can put the tank inside where it belongs if I ha
Okay, great - thanks... Tessco provides made up Heliax assemblies. www.tessco.com There is also Tally. www.tallycom.com Thanks 73 Jim W7RY --Original Message-- From: Doug Ronald, W6DSR Sent: Tuesday,
But neither of those appears to pass the nitrogen. I would have to string a separate hose just for that... For only 30' I would use FSJ4 or LDF4 with an EIA on one end and a DIN on the other. These c
I have a NOS 500 foot roll of military spec RG-218 I'll never use, and would like to sell. This coax isn't exactly low loss, but at HF has decent specs. It will handle 5 kW average up to 1 GHz, 2.4 M

I have a heliax cable ordered from Tessco which I paid a small fortune for, which has an open connection on at least one end. When I received the cable, I checked with an ohmmeter, continuity end-to-
Thanks - It's exactly those instruction that I didn't have. No installation instructions were given to me with the cable, not that I would have expected them to be. Tessco has already contacted me, a
Okay, as long as we're talking VNAs, I have a question: I am making an automatic antenna tuner, the sensor of which is a pair of AD8302s, and a pair of AD8362s. I made a 36 dB Tandem Coupler which ha
