Antenna Length Calculator

We all know how much Bob likes a spreadsheet, so here’s one that may be of interest to the club.

I have encountered the problems of trying to adjust antennas to the resonant frequency,

I decided to apply my maths skills and have come up with the attached.

Basically, you enter a number of values for;

Target Frequency

Frequency you want to be resonant at and if your antenna is ¼, ½ or whatever

You then take some vswr readings, and from there, it calculates the amount you need to increase, or decrease the antenna length.

Problem with the forums

I’m sorry but I’ve had to temporarily disable the gallery as the lastest update conflicts with the bbPress forum

I’m sure a fix will be rolled out shortly and I’ll enable the gallery as soon as I get the fix.

Website layout

After some discussion with Cambell and Bob the other night about how the website looks, I've made some changes to bring the news posts to the front while keeping the forum posts visible in the sidebar.

Let me know which style you like better (news and photos or forum centric)

There is a limit to the amount of changes I can make to the layout using the existing theme (there are many others I haven't tried)
