2.4 GHz WiFi Larsen Antennas
Posted: Sun Jan 16, 2005 8:22 pm
Anyone needing a mobile antenna for WiFi (2.4 GHz) use should consider the Radiall/larsen (formerly Larsen Antennas) improved NMO mount antennas. The specialized NMO mount is designed for operations above 1 GHz (up to a max freq of 6 GHz). It uses a coax pin type center connector, rather than the NMO's typical button top design. It can be converted in the field in a matter of seconds to perform below 1 GHz by simply replacing the center connector with the standard type.
I have posted some useful links below. They have an open twin coil design with 7 dB omnidirectional gain, or a closed coil design with 5 dB gain. They also have a very short transit style ruggedized WiFi antenna.
We have used the open and closed coil antennas with our MW-800 MDT's, and we strongly prefer the twin open coil design. It's less obtrusive, and 7 dB really rocks! We can typically hit the T-Mobile WiFi systems at Starbucks from a half mile+ away, as long as it's line-of-site. Our antennas are mounted on top center of the vehicle's roof. The MW-800's optional WiFi internal transceiver is rated at 100 mW output.
Check it out, and enjoy!
