And, do you even have to purchase them?

I tend to loose small antennas alot, and I've been buying them on ebay
or the like but I have an idea that there should be some type of electronics
store that would have some equipment. Maybe a radio or ham store?

On a side note, I currently have the scissors from a pseudo-swiss army knife broken off, and clamped to the lead on the sp-rmc connector of my lucent card ..
then its touching the rest of the knife .. that gives it a bit of a gain ...
