[Milsurplus] Antenna Tuner TN-174/GRA-4 Question

[Carl Reinemann]

I lucked out at a garage sale and picked up a BG-102-A Bag filled with
antenna gear, Lamps, cords, for wire RL-22 reels, extra spools of antenna
wire, halyards, a couple of signal corps 100' tapes (can double as an
antenna) and the TN-174/GRA-4. (the lady wanted $10 for everything, I
figured it was a great price for what she called old army crap).

Anyway, my question is, I have a 60' end run long (single) wire set up as
my primary receiver wire I use for my BC-348, SCR-264, and my Angry-5
(switched for each).  Would it makes sense, or worth it to use the TN-174
to tune the wire? I hooked it up to the Angry 5, and the neon light glows,
and instructions say to tune it to the brightest output, but it doesn't
seem to dim or brighten, pretty constant. Is this helpful to my setup, or
more of a hindrance?
