7 dBd Omnidirecctional Base Station Antenna for the 23 cm
Amateur Band
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.
DESCRIPTION
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.
