TWINAX Beverage.

Yesterday I mounted a second Beverage antenna. With 250 meters exactly the same length as mine mounted weeks ago, with the same angle. Identical uprights, identical wire spacing. The big difference is in the feed line. This is now done with a symmetrical TWINAX cable, so the topic of equalizing currents and their interference is completely eliminated. The TWINAX feed line goes directly into the station where it is converted to an asymmetrical coax cable just before the antenna switch. The construction of this antenna is a luxury, but only this way you can compare directly and 1:1 whether this variant receives better.

Cambodia, 918 kHz.

Radio National Kampuchea can sometimes be heard from the station in Phnom Penh – Kandal Stueng after 22.00 UT under interference on the mediumwave 918 kHz. September 21, the station announcement at 21.58 UT at the beginning of the transmission was easy to follow here in Salzburg. WinRadio G33 Excaibur PRO/CSO, 100 mt. Beverage.

Polish balloon experiment on 14.2 kHz

The operator of the Polish balloon experiment on 14.2 kHz on September 12, 2020 replied today to the screenshot of my reception experiment. As Tomasz A. Miś from the Babice Transatlantic Radio Station explained, the radiation pattern of the antenna changed due to the changing distance between the radiator and the conducting plane, furthermore the gain in height also played a big role for reception – at the moment it looks very promising and yes, that is most likely the balloon. Again a nice example of how we amateurs with our limited possibilities today can receive and display even the smallest signals. The proHFT KNA-6DX Whip antenna has once again excelled itself.
