I built this years ago as a quick antenna for receiving and transmitting. It is name after Havana Cuba's Arnie Coro, since He came up with it over 20 years ago.

1. Take a 45 ft/15 meter 52 ohm Coax, or multiples up or down.
2. Dress it as center conductor and braid on both ends.
3. Solder a 50 OHM resisitor on one end, connecting the center and the braid.
4. On the other end, solder a piece of coax. with braid to center conductor, center conductor to braid. On the other end, solder a PL-259, or whatever your rig accepts.. Then connect it to your receiver/transmitter.
5. You now have a balanced, low noise antenna. I would suggest a 10 watt or hgher resistor for the amount of power you are going to use if transmitting.
