A VHF Superturnstile Antenna comprises of a pole mounted ‘crossed’ radiating elements fed in phase quadrature. Also, the horizontally polarised antenna employs the familiar “Batwing” radiators as seen in image below.
VHF Superturnstile Antenna Features include:
- Suitable for top mounting on existing towers
- Simple and economical installation
- Wide bandwidth
- Radome protection available for severe weather conditions
- Inherent lightning protection
- Wide range of gains available
- Available for single or double main transmission line
- Multi channel options available
Furthermore, the Superturnstile also provides an omnidirectional or occasionally a figure eight, horizontally polarised pattern. It provides excellent and reliable service in the Low, Mid and High Bands.
More frequently it also provides a medium power single channel antenna. We also offer custom designs for two or even three channel operation. Both analogue and digital transmissions are equally possible.
Each bay of the antenna consists of four galvanised radiating elements of the familiar Batwing shape. The radiators mounted at 90 degrees to one another around the tubular steel supporting pole.
The top and bottom of each radiator solidly connect to the pole. This forms a very strong and robust mechanical assembly. The direct connections also provide a very low impedance path to ground. Excellent protection against lightning discharges is provided.
Stacking an appropriate number of bay assemblies one upon the other, spaced approximately one wavelength apart provides the required antenna gain.
Moreover, three standard sizes of Batwing radiator assemblies build up the complete range of Superturnstile’s covering the Low, Mid and High Band VHF broadcast channels. Custom radiator designs are available for some dual channel requirements.
