 Looks like they might be using a basic dipole type setup for the driven
element. which is actually 75 ohms nominal, as they mention using ring
terminals on the coax.
 Not a bad basic design, but I don't like PVC for antennas other tan a
portable like the tape measure antenna I made for fox hunting.
 Hmm, they could be also using a hairpin loop to bring it to 50 ohm, as I
just recalled that how my tape antenna is matched. If cut right, it will
come out 50 mum and match quite well.
 I live in desert country, lots of hot heavy sunlight, and this deteriorates
PVC, fiberglass and many plastics drastically...

 I think I like the Arrow designs a lot more, aluminum for the boom...
 YMMV
