Making 3 el 40m beam with coils wideband
A few options exist for 40m beams, e.g., see 40m beams at JK Antennas. Full size beams cover the whole band but they are heavy, about 70kg for 2 el and 150kg for 4 el. Beams shortened with coils are Read more

SWR of antennas on my new tower were too good because of high coax losses.The coax cables were as follow: 25′ jumper of RG213 on top 100′ of LMR600 to the bottom of the tower 120′ of LMR240 to a Read more
I bought the TW-32-XL beam (2 el on 30, 17 and 12m) from Mosely to gain directivity on 30m. I am not operating on 30m much and beverages provide a receive directivity, but it would be nice to have a Read more
Once the GXP antennas were up, there was time to test the SWR curves. 20 and 10m were fine but in all antennas the resonance on 15m was too high, with SWR at 21.00 MHz > 2:1. The 15m Read more
A good contest station needs Yagis in fixed directions so that a multiplier can be worked right away. I bought two GXP 11-3 to be put on a 36m tower, just below GXP 17-4. One was to be put at Read more
My 4 sq did pretty well in the ARRL DX contest and also in CQ 160 SSB. But it was noisy. Perhaps because the elements were not tuned, with resonances from 1.78 to 1.84 MHz I decided to tune the Read more
My 160m transmit signal with the shunt tower was OK but not great. In contests, I heard many DX stations well but could not work them until the conditions were better. Definitely I was in the middle of the crowd. Read more
The installer lifted the GXP 17-4 antenna to 110 ft and could not get it any higher. He arranged for a younger installer, who was waiting for good weather on a weekend. All while the 40m element was grinding in Read more
I decided to add an extra 120′ (36m) tower to have a better signal in contesting. My signal from the current 100′ (30m) tower is not competitive on 20m and 40m so I decided to upgrade a 2 el 40m Read more
Austria is 80% mountainous. Wherever you are in the mountains, they are zillions of ski lifts or gondolas. Many of them are open in summer for tourists. Gondolas go up from downtown Innsbruck way up. A restaurant there is perfect Read more
