LHCP Helical L-Band Feed (1550mhz center)

This is a LHCP L-Band Feed with a center frequency of 1550mhz.

I used these measurements from uhf_satcom for the construction: http://www.uhf-satcom.com/lband/

You will also need:

• 2mm thick Aluminium plate (20x20cm)
• copper cable (i used 3.2mm outer diameter including the insulation)
• sma flange (or similar)
• m3 nuts and bolts

And some tools like a rechargeable drill and a screwdriver.

UPDATE:

• 06.11.17 -> Added a RHCP version for non Dish use on request
• 01.12.17 -> Added a 7 turn version of the feed, could give a little bit more gain
• 28.01.18 -> Added a 8 turn version with 12mm spacing and space for a copper strip match
