Antenna Phenolic Tube Length?

[Matt Anderson]

I need to know what is the correct length of the phenolic tube that the reel antenna feeds through from the inside to the outside of the aircraft. Thanks

I presume that you have the L-5 parts catalog. Give me the 76- part number and I’ll see if a drawing exists.

Should be 72002. It’s not in the set that I have access to.

It took a little work to get to the bottom of this. The mast, which is called a “conduit”, was Government Furnished Equipment, so no dimensioned drawing exists in the blueprint set.  The p/n was MI-5211-10. The antenna installation drawing 76-72003 is not in the NASM blueprint set either. Luckily, the parts list on the radio installation drawing 76-72100 indicates it was 10″ long. Doesn’t give a diameter or wall thickness.

Tube is 11 7/8″ long. Looks like .125″ wall thickness.    3/4″ diameter.

Measured off of an original part.

Well, of course your tube would be longer! You wouldn’t admit to anything less, now would you? Harhar. Bad adolescent humor. but I couldn’t resist.

Thanks for the responses. Looking at the drawing 76-2100 the 10 inch conduit is the flexible hose the feeds into the 11 7/8 inch phenolic tube
