JLVP – Low power Vertical Dipole

JLVP-Low Power Vertical

Vertical Dipole FM Broadcast Antenna Series

JMVPThe JAMPRO JLVP is a low power antenna designed specifically for omni-directional translator/booster applications. The simplicity of the JLVP design gives low power stations the flexibility needed to meet their individual requirements. A stacking harness may be used to add multiple bays to achieve the required gain. Field tunable from 88 to 108 MHz. Higher power ratings available upon request. The antenna features: VSWR 1.5:1 or better ±150 kHz. with type “N” Input. 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.
