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.
