I need some help... I've been going over the ARRL Antenna Book (Vol16), the ARRL Handbook, Reflections, Physical Design of... and Carr's Verticle Handbook and can't find any BASIC information on what a capacitance hat does, how to design them, etc... Please, a quick lesson or a point in the right direction would sure help!!!! Thank You! Dino...k6rix@arrl.net
