It's the reference to termination resistors in the SPX data sheet that bothers me.

You mean this part of the SPX data sheet that screams "dummy load"?   :-)

"Tower guys are made of tough
polypropylene rope. The resistive terminations are
mounted in protective, ventilated containers."

(Polypropylene, unless some special UV inhibited stuff, is terrible in sunlight. Nylon is much better. Polyproplene lasts about a year or two here, while typical nylon lasts a dozen years)

Any antenna that says "no tuner required" and covers all frequencies with a low SWR should raise the snake-oil caution flag.
