Spider Antenna SO239 Dual-Band VHF/UHF for Motorola Radios, 10m Cable, DP4 Adapter

Description

The “Spider” antenna is designed to enhance the reception and transmission of portable radio signals and, consequently, increase communication quality and range. This is achieved by elevating the antenna (5–15 meters) and, as a result, increasing line-of-sight radio communication for reception and improving the received signal, similarly for signal transmission. The effective operating bandwidth of the antenna is approximately 12–14 MHz.

The antenna is developed according to the requirements of military and law enforcement agencies and is designed for their use. It is made of flexible elements, allowing it to be folded during movement or active operations. The antenna has proven itself excellently when operating in field conditions during combat missions in various weather conditions, in challenging terrain (elevation changes), dense forests, etc. The radio communication range for portable radios of various manufacturers is significantly increased (2–3 times).

The antenna can be suspended at any height (building roofs, trees, poles, towers, etc.). It is convenient to use when it is necessary to provide radio communication from cover (dugouts, trenches, foxholes, basements, etc.). In this case, the antenna is deployed externally, ensuring both personnel safety and reliable communication.
