Cross Polarised Yagi FM Radio Broadcast Antennas

FMCPY2 Cross Polarised FM Radio Broadcast Yagi 2-Stack Array The FMCPY2 is a Cross Polarised FM Radio Broadcast Yagi covering the entire band 87.5 to 108 MHz at better than -20 dB return loss.

Key features of this model are :

Full FM band coverage permits multiple broadcast frequencies and antenna sharing.
Cross polarisation for true circular field.
High power and gain achievable.
Long service life.

Constructed from aluminium, the antenna consists of 2 cross beams delivering a circular eliptical pattern. A power divider and branch feeder cables (not supplied) connect to the two inputs. This Yagi is available with N-Type Female connectors for 1,000 watts power per bay or 7/16” Female DIN connectors for 4 kilowatts per bay.

The antennas can be mounted in stack array formations for increased gain and power (as pictured above). U-Bolts are supplied for mounting to a mast between 50 mm and 90 mm in diameter.

A reflector screen is available for a restricted cardoid shape radiation pattern at the rear.

NOTE: Each FMCPY2 Yagi requires 2 branch feeder cables from a Power Divider. One feeder cable must be 90° electrically longer than the other. Contact ZCG Scalar for further technical advice.

Cross Polarised Yagi Y200CP Series

Y206CP Cross Polarised Yagi Antenna for FM Radio Broadcast These cross polarised Y200CP series Yagi's for FM radio transmit and receive are available in 2, 4 and 6 element models. 2 sets of elements are arranged in a diagonal cross pattern. The 2 driven elements are at 90° phase shift.

Constructed from either aluminium or stainless steel, the Yagi’s are supplied with a 2-Way Phasing Harness and will cover any 10 MHz bandwidth within the FM frequency range 88 to 108 MHz at better than -20 dB return loss. Depending upon the number of elements, 3 dBd, 7.5 dBd or 9 dBd gain is achieved per plane.

Y202CP Cross Polarised Yagi Antenna for FM Radio Broadcast The major benefits of this cross polarised design include :

Eliminate multipathing due to reflections and refractions,
Circular eliptical radiation pattern for improved propogation, and
10 MHz bandwidth permits multiple frequencies and antenna sharing.

The Y2300 or Y2300SS heavy duty right-angle clamp is recommended for mounting these Yagi’s to a mast up to 50 mm in diameter. For the 6 element model Y206CP, the YS1 single 2.5 metre strut kit is highly recommended to support the long 5 metre boom. Both the mounting clamp and strut kit is available to order separately. The 2-Way Phasing Harness supplied is terminated with an N-Type Female connector rated for 250 watts power.
