7 dBd Omnidirecctional 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.
