Ham satellites generally operate cross-band: you will generally need an UHF...

UHF Amateur Satellite Antenna (QFH) An independent review of this antenna was published in the November 2008 issue of QST Magazine [Ford, Steve, WB8IMY, "SHORT TAKES: Antennas.us 70-cm Satellite Antenna", QST Magazine, November 2008, pg 72]. The UC-4364-328 is a compact Quadrifilar Helix Antenna (8 cm/3" OD x 16 cm/6" H) designed to operate through Amateur Radio satellites, without requiring an antenna rotator. The original goal of this product was to offer Amateurs with severe space or...

Full-Size Amateur Radio Satellite QFH Antenna description The UC-4364-531 is a full-size Quadrifilar Helix Antenna (8 cm/3" OD x 30 cm/12" H) designed to operate through Amateur Radio satellites, without requiring an antenna rotator. The goal of this product is to offer Amateurs with space or community restrictions the ability to receive 70 cm HamSat signals, and communicate through orbiting repeaters (transponders). Ham satellites operate cross-band: you will generally need a VHF uplink...

UHF Amateur Satellite Antenna with built-in Preamplifier/LNA The UC-4364-513 is an amplified version of our model UC-4364-328 ( UC-4364-328 page ). It is a compact Quadrifilar Helix Antenna (8 cm/3" OD x 16 cm/6" H) designed to receive Amateur Radio satellite signals, without requiring an antenna rotator. This 70 cm band QFHA incorporates a 15 dB Low Noise Amplifier (LNA) near the antenna's feedpoint, providing for a low overall receiving system Noise Figure (and sensitivity). By having an LNA...

A broadband, rugged, mobile radio antenna featuring a high ESD (ElectroStatic Discharge) isolation. With modest dimensions of 1.5"/4 cm (OD) x 4"/10 cm (height), this antenna radiates with a typical peak omnidirectional gain of +5 dBil, when mounted on a large metal surface of at least 16"/40 cm radius. This antenna will survive a 20 ft drop onto asphalt and continue operating (see Drop Test results) Internally, the radiating element is DC grounded and the feedpoint is DC isolated beyond 1 kV....

Model VL-2901-D496 is a small Amateur Dual Band, VHF/UHF Antenna (145-148 MHz, 2m and 420-450 MHz, 70cm Amateur Radio Bands), designed for mobile platforms (vehicles) with height restrictions. Measuring only approximately 4" (10 cm) in diameter and 6" (15.3 cm) tall, this antenna is a very efficient Low Profile radiator. When installed properly on the metal chassis of a vehicle, the VL-2901-D496 will perform comparably with a full size 1/4 wave monopole antenna. For optimum operation, install...
