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: VHF Antennas
Posted: Mon Jan 30, 2006 9:06 am
I am looking information on an antenna, I dont know if I am in the right place, i was wondering if someone could help me out. I am looking for an antenna to receive around 50 Mhz, It has to have high sensitivity and high receiver gain. Can you recommend the best types. It has to be as small as possible.

This could be tricky! High gain antennas at VHF, and in your case 50 MHz, become very large indeed. Say, for example, you just wanted a gain of 10 dB, well at 50 MHz this would require an antenna with an effective area (Ae) of 28.65 m^2.
With more details of what you require I'm sure we could find a suitable alyernative.
