*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.

I want to say that antenna (TRI10) is AWESOME! It construction is first rate and performs even better. SWR is perfect across all 3 bands. I have it at 15 meters up. Purchased from USA supplier HRO.
In WPX CW 2023 I easily cruised to a SOAB LP TS victory in USA, all because of this antenna. So, if you hear WC4E / N4AO in a contest, it’s this antenna!
I highly recommend this antenna! I’m thinking about getting another TRI10!
