*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.

This antenna is very well constructed and very robust
Assembly was very easy with all hardware very well identified
SWR was excellent 1.2:1 on 15m SSB and 1.3:1 on 10m SSB
On air performance was excellent at 12m above the ground – certainly the same performance as my previous 10m 4 element monoband yagi
In conclusion an excellent antenna
