Omnidirectional VHF Air Band scaled coaxial monopole dipole, white, 118-137 MHz, specify 3%, 100W, 0 dBd – 2.1m

Omnidirectional VHF Air Band scaled coaxial monopole dipole, white, 118-137 MHz, specify 3%, 100W, 0 dBd - 2.1m

Product code: B18

The B18 omnidirectional coaxial monopole antenna is an effective and economical VHF Air band fixed position dipole antenna, suitable for VHF Airband communications between aircraft (air) and air traffic control (ground). The omnidirectional signal propogation of the B18 Airband communications antenna suits a central installation location with equal signal propogation. For narrow channel exclusion we recommend utilising a ZVBF-136AB in-house manufactured and tuned single cavity filter to ensure channel interference or cross talk is minimal.
