having fun with RF

Use a VNA to analyse your antenna

July 20, 2024 By: Chris G3YHF Category: Club, Fun, News, Training

Tiny VNAs can now be bought cheaply.

Here’s one Lee G0MTN used to test his rebuilt band-pass filters.

But how can we use them to analyse our antenna systems and improve their performance?

Wythall Radio Club members will be gathering next Tuesday 23rd. July for a practical workshop.

We’ll be using a VNA to analyse some portable antennas.

We will plot SWR over a given frequency range and display this as a line graph. And see what else the VNA will tell us!

As usual, 8pm at Wythall House (in the garden if the weather is ok).

Visitors always welcome – bring an antenna!

What is Amateur Radio

Amateur Radio is a world-wide technical hobby which allows people of all nationalities, religions, age groups and abilities to communicate with each other and have a lot of fun at the same time. It has a strong volunteer public service content. Go to Header Menu and read more under Amateur Radio
Training
Reluctantly, Wythall Radio Club has had to close its classroom and online training programmes after nearly 20 very successful years. There are many reasons for this and these are explained elsewhere on the website. Chris G0EYO still continues to act as Training Co-ordinator for the Club. If anyone wants advice on where to go, then please contact him via e mail g0eyo@blueyonder.co.uk. Go to Header Menu and read more under Training
Contesting

Wythall Contest Group is an informal group of Wythall Radio Club members - they organise participation in (and training for) monthly and annual contests including in-house, portable (using club equipment) and Field-Day style operations. Wythall Amateur Radio Club is affiliated to the Radio Society of Great Britain.
