I made one up yesterday,after receiving westflex 103 via a propper courier,,in other words it got here in one piece.
only problem i had was the connection of the matching stub , a little bit of a pain to do.Needed some heat on that thick coax!!!
swr is 1.7. not bad for a starting point!.swings about in the breeze quite nicely.
Also noticed less static,in other words the s7 of rubbish has gone!
A big thankyou to the peeps who done all the leg work and all the calculations, :-)
