- Pole clamp
- 3 kW balun; PL socket connection
- Mounting instructions
- Bracing material (except 20m and 30m)
In contrast to the classic wire dipoles, only one mounting point (namely the antenna mast) is required for the rotary dipoles, as they are "rigid dipoles". Thus, rotary dipoles with a rotor are rotatable with which one can additionally benefit from the directivity. The included 3 kW balun has a PL socket as connection.
The 20m antenna is a "full-size" dipole, all other versions have elements shortened by means of coils.
Monoband Rotary Dipoles are the ideal addition if you already have a beam for several bands. Mostly bands like 30m or 40m are missing and you install dipoles for them. However, these have the disadvantage of not being rotatable. The gain of a rotary dipole corresponds to a conventional dipole with reduced dimensions.
If you plan to install this dipole above a directional antenna (beam, yagi), it is advisable to place the antenna parallel to the boom of the beam below at a distance of not less than one meter.
The necessary guy material is - where necessary - included in the delivery. The dipole cannot then be mounted directly at the top of the mast, there must still be about one meter of space available at the top for the guy wire. The 20m and 30m variants do not require a guy wire.
All antennas of this series are designed for wind speeds up to 160 km/h and can be mounted safely on masts up to 50 mm diameter with the included robust mounting material.
