[Mgs] Radios

[Robert's New iPad]

   Not at all useless, Rick.
   I have long wondered why the antennae in Annapolis MD, on the point south of Naval Academy,  were so long, and your 15,600 ft measure explains it.

Broadcast FM radio dipole antennas tune at about 4 feet long. We've all seen those kinds of antennas in some cars' windshield glass. A dipole antenna for 30KHz, the very bottom of the LW band, is 15,600 feet long!
