Would anyone by chance have details of a whip antenna that is proven to work and is similar to what I am trying to construct that I could use as a starting point ? In "Antennas For All Applications", by Kraus and Marhefka, third edition, page 824, a 1/2WL over 1/4WL collinear array vertical is described that allegedly has a gain of 6.4 dBi. There is a 180 deg. phase reversing coil between the bottom 1/4WL and the top 1/2WL. The entire vertical should be less than one foot long. The 180 deg. phase reversing coil is the tricky part. -- 73, Cecil http://www.qsl.net/w5dxp ----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 100,000 Newsgroups ---= East/West-Coast Server Farms - Total Privacy via Encryption =--- |
