activities on VHF/UHF


In 2020, February I installed a 90cm-SAT-dish for RX, a 16 turns Helical antenna for TX at the wall of the house and started my first QSO on QO-100:






In Mai 2020 I made a new Helix antenna. The base plate is 100mm x 100mm with a hole of 40mm. The wire of the Helix has a diameter of 3,5mm. The connector is N female.

 


Return loss at 2400,2 MHz is -26,6 dB

 




 I mounted the Helix antenna in front of the LNB. A small plastic bucket with a lid protects the Helix antenna from rain and snow.
