7 dBd Omnidirectional Base Station Antenna for the 23 cm
Amateur Band
DESCRIPTION
The CXL 23-7C/… is a 7 dBd, vertically polarized, omnidirectional base
station antenna, which covers 1240 – 1340 MHz in three models.
The antenna is provided with the type “C” universal fixing bracket. The
epoxy coated cast aluminium bracket and accompanying stainless steel
“U” bolts are suitable for the most severe marine environment.
The CXL 23-7C/… is suitable for 27 – 65 mm dia. mast tubes. The
coaxial feeder cable can be routed either internally or externally to the
support tube.
The antenna has excellent VSWR and gain characteristics and is highly
suitable for repeater operation.
The radiating element of the antenna is housed in a sealed high quality
tapered glass fibre tube providing low wind loading and excellent all
weather performance.
The antenna is DC grounded for static discharge protection.
The CXL 23-7C/… is a vibration-proof, slim-line, corrosion resistant,
modern style base station antenna.
