You may explore how to fabricate a dipole with your RG58 and Thu, 25 Jun 2009 08:59:36 GMT VR2BrettGraham http://groups.yahoo.com/group/spiderbeam/message/1697 http://groups.yahoo.com/group/spiderbeam/message/1697 ... Responses so far missed that what you propose to do is effectively using the coax as a large diameter wire. The velocity factor you quote (which would need Wed, 24 Jun 2009 21:12:26 GMT DF4SA http://groups.yahoo.com/group/spiderbeam/message/1696 http://groups.yahoo.com/group/spiderbeam/message/1696 Hi Steve, unfortunately the concept that you can use coax cable for wire elements and thus shorten the lengths by the velocity factor is wrong, even though it Wed, 24 Jun 2009 20:08:24 GMT Rick Westerman http://groups.yahoo.com/group/spiderbeam/message/1695 http://groups.yahoo.com/group/spiderbeam/message/1695 2 points: 1. If you use anything except the exact same wire Spiderbeam uses (CQ532), you will spend an awful lot of time adjusting element lengths.

I need them for my new project. I will ask DL6XK to collect them.

We are having a joint booth again with APPELLO. Our booth number is A1-413 and we will appreciate Sun, 14 Jun 2009 12:32:19 GMT greenhornet_au http://groups.yahoo.com/group/spiderbeam/message/1689 http://groups.yahoo.com/group/spiderbeam/message/1689 Thanks for that Joe, I thought that yagi antennas are very directional in their use and while that is fine for point to point, my use is not so defined.

I could test it Sat, 13 Jun 2009 08:59:01 GMT Igor Sokolov http://groups.yahoo.com/group/spiderbeam/message/1687 http://groups.yahoo.com/group/spiderbeam/message/1687 I have just put up 10m dipole to check on the velocity factor of CQ532 wire. My measurements show something between 0.94 and 0.95 That is calculated against Fri, 12 Jun 2009 19:35:06 GMT Bob http://groups.yahoo.com/group/spiderbeam/message/1686 http://groups.yahoo.com/group/spiderbeam/message/1686 Hi Con, will you be at the Ham Messe this year? 73 Bob, I2WIJ Thu, 11 Jun 2009 21:02:43 GMT Joseph Aldridge http://groups.yahoo.com/group/spiderbeam/message/1685 http://groups.yahoo.com/group/spiderbeam/message/1685 Joe, Ron says he is uninitiated where antennas are concerned and will probably require some detailed construction help. Personally, at the 440 MHz range, Ron Thu, 11 Jun 2009 18:08:33 GMT Joe, aa4nn http://groups.yahoo.com/group/spiderbeam/message/1684 http://groups.yahoo.com/group/spiderbeam/message/1684 Hi Ron, It seems to me you would be much better off and would have better forward gain if you made a portable antenna using lightweight aluminum.
