OP: Your thoughts are legit, but you will face lots of opposition from existing users and from the developers, as these VNAs are designed to have every possible feature and are built to perform just e

Bill, Single band or multi? Because the 1:2 transformer (also use a ferrite choke) only matches the feed point essentially on one band (there will likely be some higher-order sorta-matches in there, t

I find that building RF circuits on a copper board makes things easier to build and offers better RF performance. I use "dead bug," Manhattan, and various hybrid copper board construction methods, and

Hello, Ernest, Welcome to the world of RF! First, I would encourage you to simply abandon UFL connectors entirely,as they are quite small, very difficult to work with, and are rated for only a few "in

I haven't experienced what Larry reports. In my 45 years of wrangling indoor and compromised antennas I have found that successfully -- and accurately -- modeling them is all but impossible and ultima

Ian, I haven't had a look at the photo you referenced, but I can say that, in my experience, environmental factors such as the steel roof you mentioned, plus other things such as air conditioners, att

Thanks, Roger. I have joined the VNA-F IO Group and am currently "awaiting moderation." :) Regards, Kirk, NT0Z My book, "Stealth Amateur Radio," is now available from www.stealthamateur.com and on the

Hi, gang, I was just gifted a NIB Deepelec NanoVNA-F (plus RF Demo Kit board) from 2020. This is a nicely boxed retail kit with adapters and some extra goodies. I have not yet powered it up, but the i

Hi, Barry, Did you happen to record those previous sessions? Thanks, --Kirk, NT0Z My book, "Stealth Amateur Radio," is now available from www.stealthamateur.com and on the Amazon Kindle (soon)

Interesting! My comments about needing a 10-W VNA were mostly tongue-in-cheek (COVID Madness?). I was not aware that high-end VNAs have amplifier loops. I guess I got to the party a bit late. :) I onc

That could be why! Sounds like there's room for a wideband linear amplifier kit for analyzers on eBay....... --Kirk, NT0Z My book, "Stealth Amateur Radio," is now available from www.stealthamateur.com

External RF is a big problem for many/most analyzers, expensive and otherwise. When large-enough external signals "get into" the measurement system, results are affected. When measuring BIG antennas,

Bad connectors. Bad coax. Bad wire connection on dipole (soldered, split bolt, etc). No feed point choke. Insufficient feed point choke. Intermittent external RF being "received" by antenna or coax th
