[Milsurplus] TRC-1 and mixed crystals in it

[Gene Smar]

To me, the ultimate of ironies is that the Yagi-Uda directional antenna
wasn't used much by the Japanese except for two intra-island links, AFAIK,
but the RADAR altimeters (a/k/a APS-13) onboard the Little Boy and Fatman
weapons all had half-Yagis, fed with folded dipoles, on the exterior of the
balm casings.  https://en.wikipedia.org/wiki/Little_Boy shows one of the
four half-Yagis on the middle of the casing.  The others were mounted on
similar rails at 90 degree increments around the circumference.

Yes, and we didn't reckon frequency in Hertz, either. :-)

Yes, but the term "Yagi" wasn't yet in use. In part probably because Mr.
Yagi was Japanese.

No. Three-element Yagi.
