VNA too good to be true?

Post by radiogareth » Mon Nov 05, 2018 5:30 pm

This item: has popped up on another group who use 2.4 GHz (wifi experimenters etc).
https://www.ebay.co.uk/itm/New-N1201SA- ... :rk:1:pf:0

Looks like a Chinese clone of something much more expensive, not that its THAT cheap. I've got coverage to 70cms, but it would be nice for 23 and 13 too.
Anyone tried one/got one? I found it suggested here https://www.thingiverse.com/thing:3130541/comments and have built his design Bi-quad for 13cm too. Handy having a 3-D printer :-) Its a very well thought out design.

I saw an article in CQ-TV a few issues ago. Well it must be true so I ordered the SA model for 38 to 2500 MHz coverage. I really like it. John G7ACD is a particular chap in our club and he was impressed.
Here's a mystery commercial aerial which is resonant at 340 MHz
What on earth is this one for?

It's good. About £250 Plus the calibration set.

Tempting especially at half that price. Just like the simpler MFJ259, it makes ideas into aerials and a whole lot more :-)
