Antennas

	On these pages, you'll find some of my experiences with antennes. I've received a lot of enquiries about the design of helicoidal antennas, and this page describes a version I designed and built to feed a parabola at the University.
	A quadrifilar helix antenna was constructed to replace a classic 'turnstile', which had been in use for years at home, after quite an acceptable performance. The new antenna (helix) outperformed the turnstile handily, and, in my opinion, merits more publicity!
