Shown here is the horseback radio station of an unnamed Western radio enthusiast. The one-tube set was powered by batteries and used a very short aerial. The illustration was on the cover of the February 1922 issue of Radio News, and according to the magazine (which also carried a photograph), the set operated on a wavelength of 80 meters, and provided good telephonic communication over short ranges with the ranch house.
For the ground connection, one wire was run to the horseshoe, and this was found to be satisfactory. The article did not state whether the horse was positive ground or negative ground.
