Since my Mustang is in the body shop for deer accident repairs, I'm having them fill the antenna hole on the fender (the 05-09 Mustangs have an UGLY front mounted antenna), so I need to buy or build an interior antenna. The trunk is another option because I have unused holes from my spoiler delete.
I've been Googling, but there isn't much info out there on this topic. Most people interested in custom antennas don't seem to know anything about radio theory and just buy whatever Crutchfield sells. So here are my questions:
1) Do I need an amplified antenna? Every windshield mount antenna I find is amplified. Why? Is it required to get the signal down the length of cable to the head unit?
2) Does the resistance of a custom antenna have to be a certain number of ohms? How do you measure that?
3) Can I use antenna foil tape like this to draw an antenna on the rear window? Is there a thinner version of this product? http://www.aircraftspruce.com/catalog/avpages/copperTape.php
4) How do you prevent the wire from acting as part of the antenna, messing up the optimal length and adding electrical interference from car systems? Shielded wire?
