New antenna active ZS6BKW multiband dipole!

“New wired multiband antenna is active, here you see how I build this nice antenne’

This great wired dipole (26 m.)will give you a lot of plessure on the HF-bands.
On the 20 and 40 meter band you don’t need an antenna-tuner, the SWR is nearly 1:1.1 (40 m) and 1:1.3 (20 m) ..
I have to make more tests to make the SWR great on 20 meter.

From the webpgae of OM PA1GF you can see the right values of the wires.
I made the option with 450 Ohm ‘ladderline’ and the RG213 coax cable direct to the
tranceiver. On pic.a you can see how I made the connection from the ‘ladderline’ to the wires. The ‘ladderline’ and the wires are twisted ‘litze wire’ , don’t use massive cable or line !

The next foto (pic b.) is the picture from the plastic tube (40 mm) with to blind ends.
In centre you make a hole as big as the PL-chassis, the other end you make a small notch who is used for the twinlead cable.

The last foto will give you the view how the cable is active at outside.
