wide band vhf(144-174mhz) LOW PROFILE MOBILE ANTENNA - RF Cafe Forums
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.

Wide band vhf(144-174mhz) low profile mobile antennas
are hard to find. After exploring the web for the
above device, I designed, built and fully tested
a prototype. SPECS: 1:1.5 vswr@ a BW of 16mhz or
greater, 2:1vswr @ a bw of 20mhz or better(ground
plane should be at least 3/4wave dia or better).
gain equal to a 1/4wave whip, can handle unlimited
power, has no delicate tuning caps or coils, mounts
on 3/4 inch Motorola mount, height 4 inches, installer
easy, so easy even a caveman could do it.
and tested my first low-profile antenna back in
1966, and have been in the two-way radio industry
since 1971. Have built models form 7-800mhz. This
device is for sale...............dave behee
