HRPT Helical feed support. 1700MHz Centre

thingiverse

If you need a custom mount, send me a message and I will be happy to help. There are now mounts for both 30*20 extrusion and 40mm LNB mounts. This is a 1700MHz centered helical feed with mount for use with a dish to receive HRPT signals from satellites. As mentioned, the support is centered for 1700MHz and has 7 turns. The helical groove for the wire has a diameter of 2.75mm. The mounting hole is 8mm in diameter. This design was inspired by Tysonpower's LHCP Helical L-Band Feed and hence, the installation instructions are essentially identical. Their feeder mount or mine can be used to mount the ground plate and feed assembly to a dish depending on which fits best for you. I am yet to test this, however, in the next few weeks I plan to build a hand tracked setup. I will update this page with images of it soon. EDIT: As of August 27th 2019, I have successfully received a HRPT signal with this setup although, I have not yet attempted to decode it as I am waiting for an SDR with more bandwidth.
