ve7kjr Posted March 4, 2009 Report Share Posted March 4, 2009 Just logged back on after a short holiday (you all must know what that is?) and great to see that there are others on the forum interested in making their own helical. I'm interested in getting the scanned info. Also in seeing who cracks the prototype first. Hi Chris,11PM: here in Vancouver, just got back in and remembered I had to send you the files,let me know if you got them.

chris_bollard Posted March 6, 2009 Author Report Share Posted March 6, 2009 Hey Mike Please let me know how your contruction plans go - in the interests of Trans-Tasman relations ) Just got a price from Shure in Sydney - $1755 Oz dollars. Even given the plumeting value of the Pacific peso this still seems like highway robbery. If you have success I'd love to hear about it and if you're willing toshare you plans try them out myself.

chris_bollard Posted March 6, 2009 Author Report Share Posted March 6, 2009 Just checked the HA8089 price from BH Photo. US$450. Go figure Shure Australia Quote Link to comment Share on other sites More sharing options...
Carl Cordes Posted March 27, 2009 Report Share Posted March 27, 2009 We have sold the Helical to New Zealand and Australia customers and shipping was expensive but not that much! I have often wondered what Shure dealers in other countries were charging for our antenna. Quote Link to comment Share on other sites More sharing options...
Adam D Posted March 28, 2009 Report Share Posted March 28, 2009 HI Carl The recommended retail price in New Zealand is NZ$1600 before tax. That about US$920. You can understand why Mike wants to make his own. By the way Mike, how did you go? Adam Quote Link to comment Share on other sites More sharing options...
studiomprd Posted March 28, 2009 Report Share Posted March 28, 2009 I got the feeling Carl was suggesting that folks down under order direct from Professional Wireless, and pay the nominal shipping (plus any duties/taxes)... Quote Link to comment Share on other sites More sharing options...
mikewest Posted April 14, 2009 Report Share Posted April 14, 2009 Hi folks Have not had a chance to do the build yet. The plastics company let me down but I've seen drainpipe that will approximate. I do have pix and measurements available. Any interest email me. Mike www.mikewestgatesound.co.nz Quote Link to comment Share on other sites More sharing options...

wolfvid Posted March 16, 2012 Report Share Posted March 16, 2012 the ultimate test is if the range of the Helix is greater staight on or at 135 degrees. if its off axis, trash it and start over. its not that easy !!!!!!!!!!! i have some at 1200 MHz for sale - they really work well and have been tweeked and field tested. start to work at 900 but get better at 1100 and go up to 1800 or so, still OK at 2400. somewhere between 6 and 9 db over i. 6 turns. pvc tubing, alu backplane. by a well know designer.builder in USA tweaked with an 80K $ signal analyser. the math is only 50 of the build, the others are the tweak with a good test instrument. have fun. wolf Quote Link to comment Share on other sites More sharing options...
