[Milsurplus] "Across The Pacific" PBS Documentary

[Brian Harrison]

Hi Michael,

Tnx for the response and terrific on all

That’s the only pict I know of showing Leuteritz's earliest loop development 1927-28
The spiral winding may have been a fluke or he may have gone a different “direction" (get it? :-) later
(ie the outside diamond-shaped loop antenna in use early to mid-1935 at Miami emailed last night)

Very interesting on PBM-5!
I think there’s one at Naval Air Museum Pensacola, here are picts of a visit a few years ago:

Isn’t this the aircraft Howard Hughes bought a couple of and practiced on Lake Meade (?) prior to flying his Spruce Goose?

My brother was a P3 Navigator for approximately 10 years active (then went with Lockheed)
If you are ever in NC there is a great aviation museum at the Hickory NC regional airport that is associated with the Pensacola Naval Museum (overflow storage?) including a P3-C that can be toured - picts here:

Your pictures confirm that the film accurately depicts the actual loop construction, but I have never seen a loop wound like that one before.  I am still wondering how this thing works and why Leuteritz made this departure from the traditional helically or spiral wound loops that were well established in Navy practice at the time and continue to be used in air, sea and ground DF applications today?

We went from Corpus Christi to Panama, Trinidad, Gitmo and back to Corpus Christi.  LF DF and LORAN A were the principle navigation radios used plus celestial navigation and smoke bombs dropped in the water to measure drift.  Also, I couldn't help noticing in the title photo of the Martin seaplane flying over the partially completed Golden Gate Bridge that a hatch is partially open (almost like a speed brake) on the top of the rear fuselage.  Probably someone taking photos out of the hatch?  I flew over and under the Golden Gate Bridge many times while flying SH34J helicopters out of the old Alameda Naval Air Station during my time in the Naval Reserve.
