JMVP - Medium Power Vertical Dipole

JLVP-JMVP-JHVP

Vertical Dipole FM Broadcast Antenna Series

JMVP-1R-DA with optional radomeThe JAMPRO Vertical Dipole Series of antennas are vertically polarized sidemount FM antenna systems consisting of balun fed vertical dipole and rigid coaxial feed lines. JAMPRO Vertical Dipole antennas are constructed of durable non-corrosive brass and copper. All associated brackets and hardware are made of stainless steel or hot dipped galvanized steel for many years of dependable service. The JLVP is cable fed and will handle a maximum input power of 1KW. The JMVP is fed with a 1-5/8" interbay line and will handle a maximum input power of 10 KW. The JHVP vertical dipole array has a 3-1/8" interbay feed system and has a safe input rating of up to 40 KW. The JAMPRO vertically polarized FM arrays are completely assembled and factory tuned on similar tower structures to insure proper impedance match and minimum VSWR. As an option, the circularity of the azimuth pattern can also be measured on JAMPRO's 7,000 ft. open field test range to determine the effect of the mounting structure on the antenna pattern. Custom directional patterns and reduced RFR arrays are also available.
