Circularly Polarized Quadrifilar Helix for Mast Mounting
DESCRIPTION
Quadrifilar helix antenna for fixed installation.
Two models within the 2.5 GHz band covering 2300 - 2500 MHz
and 2530 - 2660 MHz, respectively.
Right-hand circularly polarized antenna (RHCP).
Ideal for “base station” receiving antenna when communicating with
transmitting antenna on portable device (e.g. as receiving antenna on
board a helicopter communicating with portable camera on a motor bike
or situations similar to this).
The circularly polarized antenna minimizes the fading effect often
encountered in environments with reflecting obstacles.
Suitable for mounting on 1” threaded water pipe.
