CHA MIL 2 HF Collapsible 25-54MHz Antenna 128in
HF Collapsible 25-54MHz Antenna 128in
The CHA MIL whip is a broadband monopole antenna designed for portable or manpack radios requiring compact but rugged antenna systems.
If used in a stand-alone setup the antenna will cover 28-54 MHz with an external antenna tuner. To enhance RF propagation and antenna performance a ground-plane is required.
Its design has been borrowed from similar antennas utilized by many armies all over the world. The CHA MIL is very hardy, sturdy and portable (being collapsible). Un-mounted the entire antenna length is less than 29”. The 5 aluminum sections are hold together by a piece of 1/8th inch US GI MIL SPEC shock cord that can be replaced by the operator if necessary. But its 85% elongation and break point of 95 pounds properties make the 1/8th inch US GI MIL SPEC shock cord the best on the market.
This is an excellent add-on for the CHA HYBRID and the CHA HYBRID-MICRO.
Mounting Configuration: 3/8-24 Thread
The antenna system consists of:
1 X CHA MIL made of five 26’ sections of aerospace 7075 alloys.
IT'S IMPORTANT TO WATERPROOF THE UNIT BEFORE PERMANENT INSTALLATION
Use the Ideal NOALOX 4 oz. Anti-Oxidant Compound to improve the efficiency of aluminum conductor connections. This compound provides additional inner-strand and inner-conductor current paths.
Anti-oxidant and anti-seizing compound improves efficiency and service life of aluminum electrical applications
Suspended zinc particles penetrate and cut aluminum oxide
Provides additional inner-strand and inner-conductor current paths for improved conductivity and cooler connections
Reduces galling and seizing on aluminum conduit joints to promote good ground continuity
For use with pressure type wire connectors including screw-on, tap, service entrance and split-bolt
