Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
page, please do.
Below are all of the forum threads, including all
the responses to the original posts.
Post subject: Antenna Gain
Posted: Wed Sep 14, 2005 12:44 pm
As part of a radar project it is necessay for me to do null steering using FM dipole
antennas (88 - 108 MHz). I intend to place a null in the dipole polar pattern in the direction of
the transmitter. My question is: Is is better to use FM dipoles that have a gain in the order of
10 or 11 dBi (the likes of which sold by Lindsay Antennas out of Canada) or simply using
omnidirectional FM dipoles?
