The Jampro horizontal ring series of antennas are horizontally polarized sidemount FM antenna systems consisting of a side-mount dipole and rigid coaxial feed system. Jampro horizontal ring 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.
- Designed for Low, Medium and High Power use
- Excellent “HD Radio” Performance
- Superior VSWR Bandwidth Horizontally Polarized
- Available for 88-108 MHz
- DC Ground at each bay for lightning protection
- Optional Radomes available for JMHP (shown) & JHHP
- FCC Directionalization available
The JLHP is cable fed and will handle a maximum input power of 1 kW. The JMHP is fed with a 1-5/8” interbay line and will handle a maximum input power of 10 kW. The JHHP horizontal ring array has a 3-1/8” interbay feed system and features a safe input rating of up to 40 kW.
The Jampro JMHP & JHHP horizontally polarized FM arrays are completely assembled and factory tuned on similar tower structures to insure proper impedance match and minimum VSWR. The JLHP is supplied as a field tunable LPFM/Booster/Translator antenna.
As an option, the circularity of the azimuth pattern can also be measured on Jampro’s 7,000 square ft. open field test range to determine the effect of the mounting structure on the antenna field pattern. Custom directional patterns and reduced RFR arrays are also available.
