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.
