Piper L-4 information
 

Dear Gentlemen,

I have been commissioned for a couple of illustrations for a book dealing with the presence of Brazil in Italy, during the Second World War.

I am now working on the Piper L-4H drawings. The Brazilian Grasshoppers used to operate with a diverse of the standard radio equipment; I believe it was SCR609/610:

Unfortunately, I wasn't able to figure out how the device was installed inside the cockpit. My doubts are as follows:

Is the antenna used on aircraft the same 13 stage 12.8 feet telescopic antenna used by ground forces?
How was the antenna fixed in the aircraft? Did it share the same attachment point of the standard mast/cable antenna?

Here are two more photographs showing what seems to be the same radio/antenna mast: in the first one, it seems the mast came up to the rear wood base of the aircraft, but how it was fixed, and how it was connected? I can't see the antenna in the second photo. Surprisingly these are the only two images I found so far letting me see something helpful.

Thank you in advance for any help.
