The antenna in the photo was made by Maxrad (PcTel). I have others that appear identical from Antennex (Laird). I couldn't find a similar antenna in either online catalog. The one's supplied by Motorola use a heavier gauge wire which I guess(tm) were Antenna Specialists (PcTel) like this: http://www.ebay.com/itm/321096706872 This is the closest equivalent that I could find: http://www.antenna.com/artifacts/2012511BASELOADEDNOGROUNDPLANEANTENNAS.pdf I would advise against using this antenna for 152 Mhz and suggest you get a real 1/4 wave or 5/8 wave antenna. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |
