Jeff Wexler Posted November 17, 2006 Report Share Posted November 17, 2006 That's a wild looking antenna. I would love to hear from someone who has used this product or from someone who knows a lot more about RF and antenna theory than I do. SHURE's write up is quite extensive but they are obviously pushing the technology as an alternative to some of the sorts of antennas we use now. - Jeff Wexler Quote Link to comment Share on other sites More sharing options...
old school Posted November 17, 2006 Report Share Posted November 17, 2006 Hey yea, if looks count, I'm in. I hope someone tests one soon and reports back here, I need to spend more money, just don't tell the long suffering Mrs Chamberlain.

Philip Perkins Posted November 17, 2006 Report Share Posted November 17, 2006 I've seen these mostly as TX antennae for wireless in-ear monitor rigs @ concerts. I'd be interested in a shoot out w/ log periodic and yagi antennas for body-pack TX work w/ actors on location. Philip Perkins Quote Link to comment Share on other sites More sharing options...
Eric Leonard Posted November 17, 2006 Report Share Posted November 17, 2006 Helical antennae are designed - specifically - to receive circularly-polarized signals (as long as the transmit and receive polarization-direction - left or right - match). Circular polarization is often used in satellite transmissions, and helical antennae offer a decent compromise in size/performance versus parabolic dishes. Its circular polarization also makes it an excellent antenna for receiving vertically or horizontally polarized signals (read bodypack transmitter with a vertical or horizontal antenna) and gives it a slight tactical advantage over a more common yagi (or shark fin) antenna (which should match the polarization of the transmitter). In field experience I've never found helicals to produce a profound RF advantage to yagis, and the trade-off is they're not as compact or handy as yagis (or as cheap!). My .02.

Guest Jeffrey Colon Posted December 14, 2006 Report Share Posted December 14, 2006 James at PWS is usually the Freq coordinator, wireless guru for things like Superbowl where there are hundreds if not thousands of Rx Tx sytems in use... I would take whatever advantage I could to keep things running smoothly in those type environments... Last SB game I worked, I submitted 11 different frequencys... all but one were disallowed. BTW, James is one heck of a good guy. Jeff C Quote Link to comment Share on other sites More sharing options...
