Simple and Compact Design
Despite it’s square shape, don’t be fooled, this antenna gives true circular polarization exactly the same as a circular shaped antenna would do.
The antenna is a simple, compact design made of lightweight aluminum welded together, not bolted, this means better reliability with aging and no possibility of things getting loose in the wind. It’s perfect for countries where the regulator demands circular polarization in the permit or licence.
Ideal for low-power broadcast stations up to 800W for the N type versions and up to 3.2kW for the 7-16 DIN versions.
There are three versions of this antenna, the 2 way, 4 way and 8 way with gains of 3.6dBi, 6.6dBi and 9.6dBi as shown in the specification table below.
|2 Way||4 Way||8 way|
|Gain (V+H) dBi||3.6dBi||6.6dBi||9.6dBi|
|Gain (V+H) dBd||1.4dBd||4.4dBd||7.4dBd|
|+/- 2.8 MHz||+/- 2.8 MHz||+/- 2.8 MHz|
|Impedance||50 ohm||50 ohm||50 ohm|
|Construction||Aluminium, Stainless Steel and Teflon|

The radiation plots and picture shown in this page are for the 2 way / stacked version. The 4 and 8 way / stacked versions are the same but with total gains of 6.6 dBi and 9.6 dBi
The price panel below shows the N connector versions which are all rated at 800W. Power levels up to 3.2kW are available using the 7-16 DIN connectors, please contact us for the price of these.
3D COMBINED TOTAL PATTERN
This is the combined horizontal and vertical polarization pattern of the 2 way / stacked version. Note that the ‘End Fire’, this is the lobe shooting out of the top straight up vertically is -19dB relative to the maximum gain. Ofcom, the regulator in the UK requires this to be -14dB or better, so this antenna system is perfect for legal and compliant broadcasting.

ASSEMBLING THE CYCLOIDS
Whether it’s the two way, four way or eight way antenna system, each Cycloid Dipole is easy to assemble.
As you can see in the picture below, each Cycloid Dipole is delivered in three pieces, the main body and the two vertical radiators.
Assembly is a breeze. 1. Simply attach and screw tight the vertical radiators to the main body and then 2. Swing the Gamma Match across and screw it to the feed point.
The antenna is now ready for mounting to the tower, pole or mast and connecting to the coaxial splitter cable supplied.
