MFJ-335BT
Magnetic Mount

The MFJ-335BT is a medium duty, magnetic antenna mount. It features a 3/8x24 stud mount. It has 17 feet of RG-58U coaxial cable which terminates to a PL-259 plug. The base weighs 2.5 pounds.

Important Note:
This magnet mount would NOT support the 10m/2m/440 on a vehicle.
It would be sufficient if it was merely supporting the antenna on a metal plate in an attic.
