Has anyone used a rifle cartridge like the spelunkers do ? Drill a 12" deep hole , insert a.223 cartridge snug fitting rod , ignite. Ask your spelunker friends they often use it for rock. Or - rent a Bosch electric jackhammer and have some fun .It works very well. Puts ground rods in very well also !
I've been aware of balloon antennas but my question was did the Rangers actually use them . The story must have been from the 1950s.The Ranger had in his trunk a balloon ,wire and gas tank to fill the balloon. He could reach the headquarters with normal radio but to go direct to another Ranger he needed the balloon antenna.
The show aired from 1950-1952 starring Joel McRae and contained much of the latest technical techniques used by police. The shows were from actual cases.
I was listening to an old time radio program about the Texas Rangers. The Ranger at one point sets up a balloon antenna by filling a balloon with gas to put up a 50' antenna from his car. Was that actually used ? Certainly would help in some areas as a portable antenna.
Use the vents and matching plugs in the head board.Wrap the cable as it goes through the vents to prevent abrasion. Don't be afraid to remove carpet ,padding or molding in fact it's a good idea as there are things that you don't want to disturb such as the airbag wires etc !
Rather than connect directly to the exhaust pipe and all the heating and cooling [expansion and contraction and oxidation] I used small hose clamps on the rods [1/2" dia] that connect exhaust to hanger.Make sure you scrape metal clean and use anti-oxidant goop.
