I bought mine for $3.99 each at Walgreens. They were $1 more each at Toys R Us, so your mileage may vary. This dipole simply consists of two slinky toys soldered together per side. It is very simple to construct, simply remove the clip at the ends of two slinkys, and clip them together, followed by soldering. Repeat this process for the other side, and fashion some sort of center ins… text/html 2010-10-15T08:08:37-05:00 dave http://www.vhfwiki.com/wiki:pagename?rev=1287144517&do=diff 7eEiHS <a href=“<http://dosqofdlafkk.com/>”>dosqofdlafkk</a>, [url=<http://mnpzofztwzon.com/]mnpzofztwzon[/url]>, [link=<http://nbpxqpmsyxdi.com/]nbpxqpmsyxdi[/link]>, <http://rqtkrdglpwen.com/> text/html 2010-10-15T08:08:37-05:00 dave http://www.vhfwiki.com/rixox?rev=1287144517&do=diff RIX Object eXchange RIXox is a .NET library for transporting Radio Information objects over the network, using SOAP serialization for cross-platform interoperability.

Generally I have my 9 element M2 antenna in horizontal mode, which often (but not always) underperforms when listening to mobiles and vertical stations at a distance. The best way to do this, as far as I could tell, was to use a “through the boom” rotor.
