I spent some time today working to rehab my 43′ vertical. Made from lightweight aluminium tubing, I first put this antenna up more than 10 years ago. It was last used about 6 years ago. There was so much mud and debris around the bottom I had to dig out the base. While I was working with it, I noticed the antenna could slide up and down on its mount, so after my digging was done, I put a brick under it. Tomorrow I’ll bring out the nut drivers and see if I can get it tightened. There is also a branch about 15′ up making contact with the antenna that I will need to eliminate tomorrow. I’m going to throw some 3/32″ dacron over the branch and gently pull it away this medium sized obstacle.
I upgraded the 4:1 UNUN from the one MFJ included to a newer version from DX Engineering. The MFJ UNUN made contact with vertical radiator by way of its hose clamps. The new DX Engineering UNUN would connect to the radiator by a 7″ piece of copper strapping attached to the terminal coming out of the UNUN. For some reason, I find this new set-up affords me some greater piece of mind.
I also noted that none of the radial system was not showing any connectivity to ground. I re-stripped the wires of some radials and reconnected them. However, there is a great deal more to improve the ground system. And I’ll be working to tackle that in the next few days.
From a station building perspective, I’m working towards getting the Ameritron 4 position remote coax switch in place. It will feed a few antennas that have proven to work well for me:
- 20m Delta Loop. Mounted on a 34′ fiberglass mast. This is one of the best wire antennas I’ve ever used and I can’t wait to get it back up
- The DX-LB. I historically used this as a NE-SW inverted V. It’s still up but a tree has fallen on one leg and squished it into a thorny area of scrub brush. What a pain! It’s going to take some time to extricate it.
- The 43′ Vertical described here. It’s a strong antenna with good low angle performance. I don’t think I’ve ever given it the proper ground system it deserves.
