Reviews Summary for UC-4364-328 UHF Quadrifilar Helix Satellite antenna UC-4364-328 UHF Quadrifilar Helix Satellite antenna Reviews: 1 Average rating: 5.0/5 MSRP: $93.00
Description: 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 goal of this product is to offer Amateurs with severe space or community restrictions the ability to receive 70 cm HamSat signals, and communicate through orbiting repeaters (transponders). The antenna can be ordered in either a RHCP (Right Hand Circular Polarization) or LHCP (Left Hand Circular Polarization) version along with a variety of connectors (SO-239, N, BNC, TNC & SMA). The antenna is rated at 50 watts continuous power
Product is in production.

Works like a champ!  Time owned: more than 12 months
I have the first "high power" model produced. It is the RHCP version and covers 435-438 MHz. It is mounted on a 10' pole on the roof, fed into a mast mounted SSB UHF preamp (another SUPERB product). It hears extremely well and fading is minimized due to it's circular polarization characteristics. It does equally well on transmit working VO-52 and on receive working AO-51. There are some audio recordings of satellite QSOs by K6JEB made using the antenna mounted a foot off of the ground available from their web site.

This antenna replaced a home grown turnstile moxon based on a Cebik W4RNL (SK) design that did a very good job.

I have been told that a VHF version of the Quadrifilar Helix will become available within the next 2-4 weeks. I'll be getting one of those too.
