Last Thursday for the VK1 2m FM Lunchtime Net we had Jayson (VK1JA) run a comparison between his normal vertical and then a switch over to a beam he had modified to tune up on to the higher end of the 2m band. He found definite improvements (even with the the beam just ocky strapped to the pagola and connected with RG-58 – the vertical is connected with RG-213) and he has sent through his NEC model to share.
So here is for anyone who is interested, and I've also generated and attached the pattern for peoples viewing pleasure. 🙂
(Jayson has also sent me through the model for a dual band – 70cm/2m – beam he is working on and I'll post that up shortly too.)
