Jampro’s FM medium power side-mount antennas have a proven track record of nearly seven decades. We have become a leading FM antenna system manufacturer. Moreover, our dipole manufacturing utilizes heavy-duty galvanized/stainless steel. We also aim to assure long, trouble-free service even under the harshest conditions.
JLPC
The JLPC Penetrator Medium Power FM Antenna provides CPol at 87.5-108 MHz. Additionally, the power rating is up to 4kW. Rigid Shunt feeds with Marine Brass and Copper construction also guarantee long-term reliability. The typical VSWR is 1.1:1 @ +/- 150 kHz.
JMPC
The JMPC Penetrator antenna supports a single frequency. Its high-quality construction includes Galvanized steel, Marine Brass, and Copper. Furthermore, it delivers a Circularly Polarized Azimuth Pattern at up to 10 kW. The VSWR is typically 1.1:1 ± 200 kHz.
JBCP-M
The JBCP‐M Optimizer is a Medium Power single frequency or broadband FM Antenna. Also, the Marine Brass / Copper construction provides reliability and supports up to 20kW. The VSWR is also 1.1:1 @ +/- 200kHz. Available with C/EPol & FCC Directionalization.
JCPB-M
Jampro’s JCPB-M Medium Power Directional Penetrator Antenna is a Broadband antenna system for bands 1, II, and III. Furthermore, the CPOL dipoles will support up to 5 kW per bay/element. Finally, the stainless steel construction and silver-plated inner conductors also ensure longevity.
ADB-FM1
The ADB-FM1 is a flexible, vertically polarized antenna in 2,4,6, or 8 bays or elements. Rated at 1kW per bay, it supports up to 8kW with an eight-bay configuration. Furthermore, the typical VSWR is 1.4:1 as it is a broadband antenna and does not require field tuning.
JSWB
The JSWB FM Broadband CPol Antenna design allows multi-frequency broadcasts at 10–100 kW. Each element contains quality Marine Brass and Copper. Furthermore, silver-plated inner connectors maximize electrical contact life. It also provides excellent azimuth patterns.
JCPB-DA
The JCPB-DA is a Broadband Circular Polarization Antenna with a dipole power rating of 2.0 kW or 5 kW for the M/H version. It offers an excellent VSWR without the need for field tuning. Furthermore, the DC grounding at each bay and Balun protects against lightning.
JMHP
The JMHP Ring antenna has a 10kW rating. The side-mounted product has a Rigid Coax Feeder. It supports Band II (87.5 – 108 MHz) and is HD-Radio™ ready. Furthermore, the construction includes Marine Brass, Copper, Stainless Steel, and Hot-Dipped Galvanized steel for long life.
JBVP
The Jampro JBVP antenna delivers an elliptical or vertically polarized signal. The design handles broadband and provides a VSWR of 1.25:1 over 6 MHz. It also supports medium power inputs with beam tilt and null fill facilities. Custom directional patterns are also available.
J3YF
The J3YF is a 3-element Yagi that provides a high-gain directional pattern with vertical or slant polarization. Furthermore, it is suitable for Medium to High power in the FM (Band II) frequencies. You can also expect a VSWR of 1.3:1 or better.
Our antenna construction is of the highest quality and uses Marine Brass and Copper. Furthermore, each bay is supported by a hot-dipped galvanized steel mounting bracket for utmost grounding. This approach assures long, trouble-free service even under the harshest weather conditions.
Extended Life FM Medium Power Side Mount Antennas
Moreover, the medium power multi-channel FM markets are our primary focus, and they are demanding. Most products are also ideal for multi-channel operation over the entire FM band II or 87.5 – 108 MHz.
The range of antennas simplifies coverage area design and optimization. Jampro also aims to rapidly fulfill any broadcaster’s requirements. A combination of unequal power division and varying phases also provides a wide range of customized directional patterns.
Finally, GRP Radome covers generally provide weather protection for the dipole feed points. This approach overcomes the need for electrical element deicing. Fully pressurized feed systems and careful attention to dissimilar metal junctions also dramatically increase reliability and reduce operating costs. Most importantly, the design quality remains second to none.
