QHAM 2500-RC/...
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.
Comprehensive range of accessory mounting brackets available
to make the perfect installation for your specific needs.
