Description

The 02680S antenna is a 0dB Gain, Stainless Steel Side Mount Dipole antenna, for use in the UHF Commercial Radio Communications Band. It can be used singularly where wide vertical and horizontal beam width is required. This antenna is capable of covering the entire 400-520 MHz Radio Communications band and can be used in various spacings from the vertical mounting boom, to achieve a desired H plane radiation pattern coverage.

Its robust construction ensures excellent longevity and performance. The all Stainless Steel construction is ideally suited for weather and corrosion resistance. All mechanical connections are welded for minimum intermodulation levels. All electrical connections are directly soldered. The 02680S offers stable radiation patterns across the entire specified bandwidth.

Applications

• Multi-coupled Transmitter/Receiver Applications.

• Temporary or simple installation applications.

Construction

• Stainless Steel mounting boom. 

• Folded Stainless Steel Dipole.

• RG 213 cable Tails with N Socket.
