Re: [amsat-bb] Connecting ULNA to TranSystem dipole

["John Stephensen, KD6OZH" <kd6ozh@xxxxxxx>]

You'll need another adapter machined to reuse the dipole. It may be easier
to make a new feed. See W1GHZ's home page for feed construction info.

The connector on the dipole resembles the back side of a panel-mount N panel
connector, except the center pin is smaller diameter and doesn't protrude
very far.  There might be a way to attach a double-female N-adapter. be
easier/better to make a new dipole feed?
