If you own Swan products, you'll love this catalog. Arguably, Swan's best products are found here, including accessories and antennas.
If you have the Swan twins, the 600R & 600T, there is a lot of information here.
A big thanks to Andrew, KD5PUR, for sending me a copy of this catalog. Unfortunately, the ravages of time had taken its toll on that copy, but I was able to find a like-new example.
