Network vector analysers

[sparky01737]

I'm returning to radio after 40 odd years I did a lot of RF development in the 1970s/80s, and taking my UK Foundation RAE next week. there is a mention of using NanoVna to set up and test antennas. Question is can anybody point me to a reliable source in the UK and recommend a model as there seems to be a lot of bad press and reviews regarding clones and poor quality.
Thanks in advance

I bought a H-4 3 years ago from Amazon. No issues at all with it and yes it will do antennas - just be careful to calibrate with the jumper coax in the circuit and not at the ports.

Amazon ships to the UK?

I highly recommend getting the SV4401A VNA as it's far superior in the specs; however, it is a large unit and is not for someone looking for a pocket device. For us older folks, the SV4401A uses a larger screen and is very readable compared to the other units.

After using the older models with SMA connectors I found that I really love N connectors.

The battery life is incredible too. It uses (2) 18650 batteries and is fully rechargeable.

Can get one for $300-ish from E-Bay. Amazon pricing is a joke (@ $500) but it may be different in your country.
