range of 3 to 30 MHz, is designed for easy deployment making it ideal for temporary
or emergency situations. The antenna's solid metal housings with stainless steel
wire and fittings are designed to ensure maximum life under the most adverse
climatic and operational conditions.
Being end fed the 2012/912 broadband portable antenna is quick and simple to
install, requiring a mounting point such as a small pole or tree, the other end being
attached to either a vehicle bull bar or the housing of a portable transceiver.

perform mobile whip antennas, making it excellent for use in locations such as
temporary base camps.

mobile antenna the 2012/912 end fed portable antenna is good insurance in case of
vehicle damage caused by roll overs or damage to the mobile whip antenna caused
