Radio Direction Finding Antenna for VHF

Step 3The Driven Element

The Driven Element
The feedline is connected to the driven elements directly through a "hairpin match" This was the original concept and it works well so I followed suit.
Cut a piece of solid wire (14 gauge or smaller) 5 inches long. Form this into a shape resembling a tall "ohms symbol". Strip 1 1/2 inches of cover off the coax & separate the core. Solder the coax to the hairpin as shown in picture.. Trim the excess coax wire close to the solder. The ends of the hairpin need contact with the elements but soldering is extremely difficult on the steel tape. I crimped & soldered some small connector lugs to the ends of the hairpin and these are contacting the steel under the hose clamps. The tape measure sections need to be sanded to remove any coating at the contact area.
