MONO4 10 Antenna
MONO4 10 is a full-size 4-element yagi antenna with excellent SWR bandwidth, optimum gain, and front-to-back performance. This antenna is lightweight for easy handling yet strong enough to withstand harsh weather conditions. It is perfect for use in multi-stacked arrays. A MONO4 10 stack can be configured for either maximum forward gain or positioned to cover a greater area of the world.

*Wind survival is the maximum wind speed to which the antenna can be subjected without incurring permanent deformation (calculated in the absence of ice)
RF Choke Details
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 in diameter. The 10KW version uses a 7/16 DIN style connector.
