Helix antenna For QO-100 Satellite
The Helix antenna, well known by the ham community for its efficiency
over a very wide band with low VSWR, perfect circular polarization and
simplicity to install in any dish, makes it one of the favorite types of feeds
for Space communications.
With the help from Luis, CT1DMK for coil and impedance match design and
Sandor, DM4DS, for 3D original design ideas, We developed this new Helix
especially dedicated to small Offset dishes with extraordinary results even on
small as a 40cm diameter dishes.
This type of Helix is a perfect feed system for those who can’t install a
large dish on the roof, caravan, camping, apartments, field, emergency etc.
Our Helix is 3D printed in a PETG rugged material Water/UV/RF proof.
( sorry no snow in Portugal, cannot test it here, but I believe it will be OK
🙂
PETG is totally transparent to RF on 2,4 and 10 Ghz, the total attenuation is
less than 1dB on 10 Ghz and negligible on 2,4Ghz
The installation is very easy, and several types of LNB can fit inside,
however, we strongly recommend you to use our DXpatrol LNB, as the SWR is
factory set to be 1:1 with our LNB fitted IN.
Other types of LNB might need SWR correction.
The total length of the Helix is 16CM and weight with LNB is about 0,3Kg This
Helix is suitable for Narrow band and DATV usage on QO-100.
RF connector N-type
We recommend after installation, to isolate the N-connector with rubber tape
of mass.
