One outfitting tool that I love is a good old 3 watt (were the bag phones 5 watts?) analog cell phone. In two instances it has saved much $, time, and some day maybe aid in something greater. I have reception on my bag phone in places that just amaze me. What I've always wanted however is to employ an external antenna for the phone. Buying a marine antenna for this is very costly and I can't imagine would be too terribly hard to build one for less, as long as impedence was matched and design was sound. Are there any RF experts here that could help me make a high gain antenna (or any arial that will be better than the 6" loaded one that's on the bag) for said phone? The frequency/wavelength band is known of course.
