41. [TowerTalk] Ecoflex cable (score: 1)

About three years ago I purchased some Ecoflex-10 cable assemblies from Vibroplex. These had what seemed to be very nicely made PL-259 type connectors preinstalled. (Getting lazy in my old age) It ap

I have Harris Hawks perching on my beam a lot.  There have been as many as six at one time.  I'm always reluctant to turn the beam when they are there.  They are rare in the way that they hunt cooper

Don't think so. IIRC the OP said the tubing diameter went from 4" down to 1".  If you modeled in NEC with stepped-diameter correction to get an equivalent uniform length and then took a percentage be

I thought the CM current in question came from the antenna in the first place. Wes  N7WS ... But, these common mode currents on the shield travel and radiate. Therefore, they get to your antenna, and

Yeah, but... This thread started with a question about whether to just coil up some coax or to wind a balun at the feed point to "keep RF off the coax." This sounded like a valid transmitting concern

I know a fair amount about ladderline. I use a coax-fed (with choke) fan dipole for 40 and 80. Wes  N7WS A friend of mine told me the other day he's putting up a doublet for 80/40M feeding it with a

It may be terrible, but it's better than no antenna at all. I have 72 DXCC entities worked using an inverted-V, 45' high at the center with ends barely off the ground.  Some of these with a barefoot

Not at all. FT8 decodes signals that aren't there and JT65 uses lookup tables to glean calls.  So I call them imaginary modes.  On my last FT8 QSO, and I do mean last, the DX station sent me a text m

It's a hobby . We get to choose our own metrics. I do find it interesting that my metric of DXCC countries worked is bogus in your mind while equally subjective experiences of yours are more valuable

I looked at your QRZ page.  Have you finished your project? I helped a friend install the same antenna and tilt plate on a Tashjian foldover tower.  It was not without issues.  If you are interested,

Is that correct? That's a reflection-based measurement, and has VERY poor accuracy when Z being measured is much greater than or much less than the system impedance (50 ohms). As you know, because he

I believe that's true for through measurements, however, p14 of Product Note 3577A-1 says that for reflection measurements, a full one-port (OSL) calibration is performed.   Always worked for me.  I
