Panel on C-130 vertical stab question

On C-130s painted in camoflauge they used to leave a panel bare on each side of
the vertical stab. There was a circle in the middle that was painted. What was
the purpose of doing this?

That circle in the middle isn't paint, it's - for lack of a better term - glue.
Actually, a combination of adhesive and waterproofing. There is a longwire VHF
antenna that runs from there to the spine just behind the flight deck.

Most of the C-130s I worked on were the bubble top HC-130P and HC-130N and I
seem to recall the long wires went to the leading edge of the vertical stab.
Come to think of it the bare panel seems to have disappeared on the ones I
worked on long before we went to gray. Maybe it was a change on ours.

Many thanks.

Much more likely it's an HF (High Frequency) antenna.

VHF doesn't use 'long wire antennas'

Yep.

You can operate on long wire antennae with VHF if you cut them right
(centre-fed droppy V-dipole, etc.) but there's no need to on an aircraft.

The c-130 is identical to what Gord wrote. In fact, my friends in Mojave
are seeking an STC to eliminate these wirs and put the antenna in the
vertical stab. (ie L139)

C-130s are not STCed. To change it requires a class B mod or TCTO.

That is why I wrote L139, dumbass. Do you ever get anything right, Dan?
