Whoops! I stand corrected on the loop antenna; I didn't know there were various sizes... carry on then!
Regarding the flap deployment speeds, yes indeed the original Lockheed spec for that is just silly slow at 100 kts for flap extension. Luckily, our ship has the partial Learstar mods done; the flap trailing edges are straight across compared to the standard tapered or curved trailing edge... I don't know if there were any structural mods done to the flap tracks, but flap speed are bumped up a bit. The first 10% can extend at 135 kts with the rest going out at 105 kts. The ability for flaps 10% at 135 kts is a huge help in slowing things down in the pattern... but then again, when in doubt, you can toss the gear at 145 kts. That's a huge speedbrake!
Attached is a pic of the V-speed placard riveted to the throttle quadrant; I'm assuming this would only apply to ships with Learstar/Howard mods. With a Google search of the old N9980F reg some interesting pics come up of a previous life as a '50s-'60s corporate transport and a '70s weather research ship.
