Re: Quadrifilar Helices



The Satellite Experimenters Handbook by Martin Davidoff K2UBC (1990 Pages
8-15 & 16) and it's successor The Radio Amateur's Satellite Handbook (1998
pages 10-13 to 10-15) both have details of this antenna, its use and its
construction.
I recommend this book to all satellite experimenters and users, it may be
nearly 10 years old but the principles and information contained therein
have not changed.
