Couple of months ago high wind gusts bent a support tube in my tower.
Well, yesterday was repair day. Here are some photos.
Photo taken earlier showing a bent support tube.
Winch in place, getting ready to lower.
Antenna on its way down.
Faulty support tube removed.
Not straight.
On its way up again.
Done!
improvements: Support tube is now made of steel, before it was of aluminum. Also, notice the second support bearing in the middle. Hopefully this improvements will make it hold.
After being grounded for several years my DK7ZB 50MHz-4-Element-28-Ohm-Yagi once again is up in the air.
Although it is hard to see it under the Fritzel. Looking forward to try some jt6m again.
Merry Merry Christmas all!
Had high winds here last night and here are the results 🙁
Mast tubes are bent

Today I decided to try out the pa0rdt Mini Whip design.
I have only have tested it for å few hours, but so far I find it performing a lot better on the LF and MF spectrum compared to my other Active Antenna discussed I an earlier post on this site.
On shortwave up to 20m it seems to perform about the same BUT there is a very important difference between the two; pa0rdt design dos not overload when I simultaneously transmit on other bands. My other active antenna makes all kinds of crazy bi-products while transmitting.
I think I was a bit too hasty with my first report regarding the difference in performance of the two active antennas. Now, after a little more use I think they perform almost equally. The pa0rdt whip has a bit more gain but the SNR seems to be about the same.
