A ham supply shop, R&L, was recently advertising the H4 for $59.95 and a buddy got one early this week. Today they say out of stock. But now they also show the 2.8 inch model for $49.95. Link:

The material is silver-plated brass, directly nanovna "hangs" in the air, as it were, but has adjustment with nuts for stiffness. It does not have a very rigid attachment to the base.

No problem, Terry. I'll be glad to evaluate them against the HP 'gold standards'. BTW: Welcome back from Florida! Dave

I should add there is significant info on using the vna to accomplish antenna measurements. Just google on those key words " antenna measurement using a vna "... Tek, Keysight, others have extensive

Hi Jean. The active antenna is a one port just like a Passive, however with an active element present. So you need to limit the input power if you want to probe the port where the antenna element is

hi Dave, I am looking where and what to buy. One of the VNA's is for my friend at work, the other for myself. We would both opt for the 1.5 GHz version despite the low dynamic range there. Probably

Is this an optical illusion or is this any tiny lcd on the V2? If so, Hugen, get busy and make us a 4" version. ;-) Two steps forward, one step back. 73 Glen K4KV

I think S11 noise floor refers to the floor of the return loss that can be displayed; at this point the system noise overwhelms the output of the directional coupler or bridge. Basically, it's the

Can someone explain what does "S11 noise floor" mean exactly? From the marketing perspective the product is a bit confusing. No battery and no case but with a screen. Makes no sense. Also no
