MONO3 40 is a 3 elements monoband full size Yagi for the 7 MHz!
It has a good VSWR < 1:1.5 on 300 kHz, very good gain and good F/B ratio.

No hairpins, or other devices are used to feed the antenna! You will need a good RF Choke (provided) to connect the coaxial cable to the antenna.

MONO3 40FS will be very easy to assemble thanks to the grouping and labeling of components. All hardware has been bagged by its group and labeled for quick identification!

Its construction is heavy duty type!
The element plates are made of thick U-shaped aluminum, and the elements are made more solid by horizontal and vertical tie rods!

Given the imposing size of this antenna, special mechanical solutions have been adopted to make it solid and durable.
It has a square boom made of thick aluminum, and the elements are telescopic with a starting diameter of 60mm / 2,36 inch

Mounting: Requires a rotor for large load

RF choke: 3kW included

*Wind survival is the maximum wind speed to which the antenna can be subjected without incurring permanent deformation (calculated in the absence of ice)

**The Momobeam RF Choke (standard product offering, rated at 3 KW) is made from high quality Teflon dielectric, double shielded, low loss coaxial cable with properly selected ferrite material that is sleeved over the cable that together, create a high impedance path for RF, providing high isolation between the antenna and coaxial feedline.

An SO-239 female connector is included for convenient attachment to the customer feedline and its PL-259 Male connector.

The 5 KW and 10 KW rated RF chokes (optional purchase) are made from the same materials except the coaxial cable is 10 mm diameter.

The 10KW version uses a 7/16 DIN style connector.
