1/4 Wave Antenna Calculator

I have been making a few 1/4 wave antennas lately, mainly for UHF and the GHz bands with good success, so I decided to create a calculator to simplify the process and maybe get some people who have not tried one before to give it a go.

For UHF for example, these can be made very cheaply, very easily and they perform well. Try one on 433MHz plugged into your handheld for example 🙂

A long break…

It’s been a year to the day since I last posted an entry here. I have had quite an inactive year with regards to the hobby. Work takes priority of course, but I will get out and about this year and posting a bit more on my blog / pages. I do have some things to update and new pages to add when I have the time such as constructing a 20 element 1.3GHz Yagi, building a 1.3GHz system & some PSU reviews. l also have a few messages and comments to reply to which I am getting through slowly.

It’s been a long winter but spring is finally here so it’s time to get back into the swing of things 🙂
