I'm not aware of any vertical antennas with cloverleaf patterns so I am going to assume it is a horizontal antenna (as used for BC shortwave). A horizontal dipole longer than 1.25WL tends to have a multi-lobed radiation pattern, at one point, resembling a cloverleaf. Such a pattern is pretty much four-lobed when the dipole is about 1.6WL. At shorter wavelengths than that, it exhibits more than four lobes and at high multiples of the 1/2WL resonant frequency, becomes essentially an end-fire antenna. -- 73, Cecil, W5DXP I Remember back in early 60's a number of hams in my home town built clover leaf antennas for 2 & 6 meters.. if my memory serves me right they were horizontally mounted and worked quite well for 2 & 6 Mtr AM in those days .. I used one as a novice for 2 mtrs. Novices had 2m AM priviledges back then. But I had nothing to compare it to so can't say it was better or worse tnan any other 2m antenna. Also if memory serves me right it was mad up of 3 heart shaped full wave loops condected in paralell and fed with a single coaxial line. 73 Dave Kc1di ----== 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 =--- |
