*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.
