The true circular polarization of the HSV antenna

The true circular polarization of the HSV antenna offers excellent performance for stereo operation.Each HSV is factory tuned to specific frequency in the FM Band II (87.5-108 MHz ) ranger that the customer's actual frequency to get maximum output transmission.This antenna feature VSWR is 1.1:1 in the specific operation channelState of the art mechanical design, employing the finest materials (stainless steel, non-corrosive marine brass, silver plated copper, virgin PTFE) resulting in long life service. Each antenna is DC grounded at every bay for maximum lightning protection.Impedance: 50 OhmConnector: N female៥- Extremely low power consumption

Antennas

BKG 77 Circular Antenna
This antenna constructed completely of stainless steel offers the possibility of simultaneously utilizing vertical and horizontal polarization for better coverage especially in urban areas. In order to facilitate and decrease shipping costs this model is simple to break down and reassemble when ready to be installed. It is insulated with teflon and with the appropriate connector has a maximum input of 2 kW



BKG 88 Circular Antenna
This antenna, built of stainless steel is designed for circular polarized transmission with medium and low power installations. It is factory tuned to the requested frequency, but it can be re-tuned in the field, with proper test equipment, thanks to the adjustable sliding stubs. The low cost of this antenna makes it a good choice even for systems composed of many elements.
BKG1/P Stainless Dipole Antenna


This broadband dipole antenna constructed of hot dipped galvanized steel is designed to last a long time in any weather condition. Because of its sturdy construction it can support up to 2 kw of input power with the appropriate connector. Since it has a wide angle of radiation it is suggested for omni-directional arrays. Due to the fact that is easily disassembled and reassembled, it can placed in a compact container making it very portable and inexpensive to ship



BKK/2 Directional Panel Antenna
This very sturdy antenna is capable of up to 5 kw of input power. Since it is highly directional it has a high gain. It can be easily installed on any tower face and made up of many elements. Given its considerable weight an adequate structure is very essential.


JHVP Vertical Dipole

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.


JLCP Circular Polarized
The JAMPRO JLCP is a low power antenna design specifically for omni-directional low power applications such as LPFM, Translator and Booster stations. The simplicity of the JLCP design give low power stations the flexibility needed to meet their individual requirements. Stainless steel and hot dipped galvanized steel construction yields long life. A stacking harness is included when multiple bay arrays are ordered. Similar designs by others have very low V-Pol compared to the JLCP. Result; the JLCP has better car reception and building penetration. Field tunable from 88 to 108 MHz. The antenna features VSWR of 1.5:1 or better +/- 150 kHz (200% modulation). Comes with DIN input fitting per bay. 7/8" EIA Flange for two+ bays. Provided for 2" pole mounting. Optional tower leg brackets and factory matching available upon request.


JDIY FM Circular Polarized
The JAMPRO JDIY-1 is a FM antenna designed specifically for omni-directional, low power applications. The simplicity of the antenna design gives low power stations the flexibility needed to meet their individual requirements. Stainless Steel Construction is featured for long life. The JDIY is 1,000 watt power rated for 88 to 108 MHz. The antenna features a VSWR of 1.5:1 or better. The JDIY comes with a professional 7/8” EIA female Input connection. The inner connector is silver plated brass. Two versions cover the whole US FM band.


JYFM FM BroadBand
JAMPRO FM Yagi Antenna is suitable for transmitting or receiving. No tuning needed because the antenna is broad-band. Worst case VSWR is 1.25:1. Higher power capability assures long life. Designed for continous duty service. The Jampro JYFM Yagi Antenna is constructed of stainless steel for long life. Mounting hardware for up to 3" OD pole or tower leg allows use in either vertical or horizontal polarization service. Uses real EIA flange for weather tight connections.
