Telewave ANT37D Dipole Antenna
The Telewave ANT37D is a durable, high-performance single dipole antenna tailored for VHF lowband applications such as public safety communications, utility networks, paging systems, and military communications. It offers a bandwidth of 7.5 MHz without the need for any tuning, and its design allows for the stacking of multiple elements to enhance gain and directivity.
Constructed from 6061-T6 aluminum, the antenna's base is welded to a robust, machined aluminum block, ensuring superior durability. It features a large 3.5-inch diameter boom that contributes to its overall strength.
To ensure maximum protection against environmental factors, each antenna is coated with Txylan™. This coating effectively safeguards the antenna against moisture and ice accumulation, as well as damage from corrosive gases, UV rays, salt mist, acid precipitation, and abrasive winds.
The ANT37D antenna package includes the
ANTC482 dual clamp set, suitable for supporting pipes or tower legs with diameters ranging from 1.5 inches to 3.5 inches. Additionally, it comes with one
ANTLBB element support boom and all necessary clamps for installation. Given its size and the potential for wind load, it is advised to mount this antenna on the side of a tower.
Please note that this antenna is exclusively shipped via truck freight.
