Don't make this harder than it is guys. Antennas are generally some type of a coax cable. A center conductor and an outer shield. The outer shield is just that. It shields the center conductor (by being grounded) to help keep noise out of the center conductor. The center conductor is what carries the signal to the front end of the receiver. This is typically a 50 ohm impedance for radios, 75 ohms for television, etc. You have to splice the center conductors together, insulate them so that when you splice the shield, you don't short this out on the center conductor. Also, keep in mind that when you make a "quick fix" connection, you will change the impedance of the coax cable that you are splicing. These are designed to show the proper impedance to the device it is connected to. (ie. RG-58 cable has 50 ohms, RG-59 has 75 ohms) This can cause some degradation in the sensitivity of the receiver. Make sure that your splice is sealed so that moisture can not get into it as well. This too will cause poor reception eventually. Long story short, splice both wires.
