One of the few dipoles with a proper match for 50 ohms  Time owned: 0 to 3 months
Vortex Antenna are new UK company launched in 2011. I was looking for a well built dipole, which would match the 50ohm coax. This has a gamma match. Good quality parts are used, including PTFE in the match, and Heatshrink Sleeving, lined with adhesive to provide a good seal againts the WX. The quality of the materials is very good. You can pick up the dipole at the extreem end and there is no flexing of the aluminimum. The SWR is very flat, and was almost "spot-on" using the supplied data, for setting up the element & gamma match lengths. So far I have had very good signal reports.
