I’ve contributed a new 6m Yagi for Field Day this year – an M2 Antenna Systems 6M5XHP. This antenna has 5 elements on an 18 ft boom. This antenna is fairly lightweight for its size and performs great – perfect for Field Day.
We installed it on two tower sections (20 ft) of so that we could properly adjust its tuning.
We found that we could adjust the antenna’s driven element and hairpin match for the best SWR performance with the tower tilted over and the antenna on its side. We got nearly the same SWR performance this way as we saw with the tower and antenna tilted up 20 ft off the ground.
After several adjustments with the tower up and down, we finally came up with an SWR curve that looked good.
The club purchased a WRTC tower and Triband Yagi a little while back and this Field Day will be the first time that we’ve had a chance to use this combination. We found that the phasing system and feed point for the WRTC Tribander had been misplaced so we made a replacement for these parts and we wanted to test the WRTC Tribander’s performance with the new parts.
After a quick check of the WRTC Tribander’s SWR performance with the tower tilted over, we stood the tower up and measured its SWR performance on 10m, 15m, and 20m.
The antenna’s SWR performance with its new phasing lines and feed point looked great on all three bands!
We ended the day by disassembling the two Yagi’s and taking down the tower. With this project done, we’ll be working on a falling derrick system for our third tower for Field Day.
A big Thank You! to Dave, Mike, and Don for helping with this project. It was a lot of fun!
