KMSO-FM, an adult music station serving the Missoula, MT market at 102.5 FM, has selected a cost-efficient JDIY antenna from Jampro Antennas, Inc. of Sacramento, California. The JDIY is the low-power, circularly polarized, wide band version of Jampro's famous series of "Penetrator" antennas, and specially designed for low-power omnidirectional broadcasters. Jampro’s JDIY has become popular among low-power stations wishing to conserve costs by performing their own antenna installations.
