Rx 2.4Ghz antenna questions
Remove this ad - become a site supporter!
I am using Spektrum DSM Tx and Rx and have a few 7 and 9 channel HK orange receivers.
As far as I know the active part of the antenna is only the last 31mm of unshielded wire.
I also noticed different Rx antenna lengths being sold for 2.4Ghz FrySky systems and as far as I understand the different length is only to allow better placement of the 'active end".
Couple of questions:
1. Since both FrySky and Spektrum use 2.4 Ghz can I use the FrySky Rx antenna for Spektrum?
2. I understand that that the length of the antennas are based on a quarter wave length - not sure why.. But why Spektrum are using two antennas while HK are using a single one both on the Rx and the Satellite, what's the benefit of using two antennas and should I consider adding a second one for the HK Tx?.

Re: Rx 2.4Ghz antenna questions
Don't think it matters much. I have some early HK different model rcvrs with two ants. as well as the orange 6s with the single ant. As long as they are 3 mm or 1 1/4 in. long, they work fine. I wouldn't mess with what already works fine.
Tried for my kamikazi pilots licence. Flunked the test.
