The ground may seem simple enough—and it is; but one should use a good ground clamp whenever possible, and connect it with the cold water pipe for best results, as shown here. need not give up the idea of radio, for almost anythingwill serve for an antenna especially when receiving fromnearby stations. Excellent results may be obtained witha piece of wire about 40 feet long, just strung back and 152 RADIO FOR EVERYBODY forth in a room or placed behind the picture mouldingso as to be out of sight. We know, of a man whouses an antenna for receiving from the Newark broad-casting station at a distance of 250 miles, and, on oc-casion, from Pittsburgh, some 650 miles away. The sameman receives the signals of Nauen, Bordeaux, and otherEuropean high power stations with the same antenna. The usual fire escapes found in the city make excellent antennas. However, care must be taken in. Simple vacuum tube hook-up for use with a loop that VC is a variable condenser; GL—grid leak; V—variometer acting as the feed back inductance; T—tele-phone receivers; B—*B or plate battery; FC—fixed con-denser; K—rheostat for filament current; A—filament arrangement will operate over short distances. Forgreater range a radio frequency amplifier must be used scraping the paint ofif clean in order to make a good con-nection with the metal. Sometimes a gas pipe makes anexcellent antenna, while the water pipe is used for theground. If nothing better presents itself, a metal bed-stead or bed spring serves as an antenna, with good re-sults. Indeed, the problem of the antenna need never RADI
