This antenna is the correct telescopic replacement antenna for the Yupiteru MVT-7100 & MVT-7300.
It has the correct swivel joint, and is ideal for fitment to a Yupiteru that has been purchased 2nd hand with an incorrect low-performance rubber duck antenna.
Yupiteru scanners have a reputation for fantastic performance, one of the reasons is for the antenna !
This antenna will fit all scanners that have a BNC fitting, and is suitable for base station scanners with rear mounted BNC sockets that are missing the little screw-in antenna at the top.
The specs of this antenna are better than the OEM, even with a gain of 2.15db !!!
