TDG330
Tandem Delta Antenna TDG Series 3 - 30 MHz

A high angle radiating antenna designed for ionospheric propagation over short to medium distances. Specifically designed for ground to air systems utilising high performance and reliability.

• The Tandem Delta is a derivation of the RFS series of delta antennas.
• Unlike the standard delta or other travelling wave antennas, where radiation results from a wave travelling upward to a resistive termination at the apex, the Tandem Delta does not incorporate a terminating resistor. All input power is therefore radiated and, in consequence, these new antennas have a higher gain than the standard delta. Furthermore, removal of the terminating resistor means that higher power ratings are more readily achieved.
• Because of its high radiation angle characteristics, the Tandem delta antenna is less prone to long-distance interference and local electrical noise. It is strongly recommended for high-grade communication networks.
• Tandem Delta antennas operate completely independently of ground conditions. Their polarisation is elliptical.
• RFS masts, and stub masts for this antenna, are available as options.
