Re: Stripping Coax

 

ALL- I never saved the link and I looked at Banggood.com and do not see any like the ones I had. Frankly that purchase was pre-pandemic and Banggood is like Amazon.. A collaboration of individual sellers that use the common website for advertising..

This is not the only thing I saw come and go on Banggood, Same with shipping time and is today's price what it was pre-pandemic.. Also pre-pandemic they had free shipping, then free shipping on orders over $49.. Now.. It's all different..

So- it is what it is.. Frankly at $1.65 I think the guy figured out he wasn't making money ---or-- the product was some sort of blow out sale to get rid of what he had..

Yes and thank you for posting the link. At the time of my post I was on a computer interface that was very minimal!!!

However, again thanks and that is the correct location.

Enjoy.

The ones i get have a "plug" you can rotate for RG-174, RG-58/59, RG-6U/RG8X, or RG8/9913 that sets razor blade depth..
I surplus my extras- at ham fests for a $1 more. or as "door prizes" at Club meetings trading them for tickets in the 50/50 raffle.. winner gets a whole, not a half of the stripper..
Always demand the whole stripper... This is true even if not a ham..
Re: Stripping Coax

 

Hi, Larry,

Any chance of a link or name? I've looked on Bangood and found a "universal" coax stripper which could be useful but only goes down to 3.2mm. I use a lot of RG176/4 which is much thinner. The one you describe with the plug seems ideal for my use.

Thanks - Michael.

Re: Antenna / VNA Question

 

Very good explanation Roger.

I might add to get ride of USB interference I put a choke on the USB cable and it kept it isolated and the Nano VNA calculated the same values on HF frequencies with no ground issues with it plugged in or not.

Of course if you have your hand on the VNA it does affect it.

I also have my VNA on plexiglass

Kinda reminder not to be holding on to it when making a measuremnt. Also keeps stuff away from the VNA.

Re: PC Boards for QEX Step Attenuator Available

 

What is the throughput loss with all attenuators bypassed by the
switches, at 500 MHz?

For a poor ham's step attenuator design, look here:

Works well up to about 500MHz. The blowback is very small because of the
type of "switches" used.
Feel free to order on JLCPCB. The design is under CC license.
