Ever since the introduction of the Dominator antenna, station engineers have been asking about stacking the antenna for more gain and if we were going to make a circular polarized version. The new Phazor® FM broadcast antenna addresses both of these issues with amazing results. The newly designed Phazor® with twin collinear 3/4 wave main radiators and advanced phase shifting element that radiates an additional signal in the horizontal plane.

The Phazor® antenna uses a pair of 3/4 wavelength main vertical radiators that are separated by a central 90 degree horizontal loop phase correction element. The 3/4 wavelength radiators require a 90 degree shift in phase between them before the next element can be effectively driven in the correct phase to add to the signal. An interesting requirement for circular polarization is that you need a vertical element and a horizontal element driven in such a way that the RF energy is 90 degrees out of phase with respect to each other.

This provides a unique opportunity to allow the energy in the phase shifting element to radiate in the horizontal plane by forming the phasing element into an open horizontal loop. Thereby providing a level of circular polarization, a very desired effect for FM Broadcasting. The Phazor® actually produces an elliptical polarized signal, with more energy in the vertical plane while providing compatibility with horizontal reception antennas. This type of polarization combined with the high gain achieved by collinear stacking is very effective at punching trough rough terrain.

The Phazor® is the next generation of FM Broadcast antennas built on the well known line of Dominator antennas. It provides double the gain and twice the Effective Radiated Power as the Dominator. With nearly 20 feet of radiation surface the Phazor® is the monster of FM antennas with the signal to match. It eliminates the need to stack multiple bays because the Phazor® is several effective antennas all in one. These is no magic here. The concept of collinear stacking vertical radiators has been in use for many years throughout the VHF spectrum but never applied to FM broadcast, dual polarization, or antennas with wavelengths above 5/8 wave.

We are very confident of this antennas ability to clearly outperform all of the competition!  The Phazor® antenna is known to outperform every single other FM broadcast antenna in existence, regardless of cost. Try finding that claim on an antenna anywhere else.

FAQ's

 

NOTICE: Elements used within the Phazor® antenna are officially protected under Patent Pending status. With both US and foreign Patents being applied for. The recorded date of conception on this invention is March 28, 2005 with a working prototype demonstrated on April 9, 2005. No public disclosure has been made prior to obtaining Patent Pending status. It is a criminal offense to falsely claim Patent status.

The antenna is mounted with four included U bolts that mount to the base of the antenna parallel to the mast.  Mast size can be 1-1/4 inch to 1-3/4 inch with supplied U-bolts.
