I set the challenge to build a cheap and effective 2m 3ele beam at the club last week and it looks like we’ll get a few people giving it a go. Whilst it certainly isn’t going to be a particularly scientific set of tests I hope the members will get something out of it. I plan on following it up with a run through some of the antenna modelling software that is available.
Judging will take place on the 2nd July to coincide with the next club meeting. I’m quite looking forward to seeing how inventive people will be.
By all means use the info in the club post if you want to have a go yourself. The maths may be a bit sketchy but bear in mind it was done to fit a commercially available design that I’ll be using as the ‘control’.
