UHF TV GRID KIT Antennas
GKA Series
RFS Parabolic GRID KITS are designed to be assembled into grid parabolic antennas of comparable performance to welded grid antennas.
Grid kit antennas have an important advantage - they can be packed in smaller component level packages, greatly reducing transportation costs, handling and storage problems. Assembly can be carried out with a few basic tools and is easily achieved at remote sites.
Kits contain universal mounting clamps including the panning clamp, but tower mounting tubes are not included. The mounting method allows either horizontal or vertical polarization.

FEATURES / BENEFITS
- Extremely rugged mechanical design to withstand high windspeeds (up to 350km/h)
- 100MHz bandwidth for multichannel applications
- Horizontal or vertical polarization
- Easy adjustment of azimuth and elevation
- Broadband unpressurized feeds, with no trade off in gain slope characteristics
- Corrosion resistant aluminium tube reflector, hot dip galvanized mounting, stainless steel hardware.
