  1. Isn't that just a pocket J-pole? If so, $50 seems awfully expensive, even with cord and a variety of BNC adapters thrown in...

  2. I agree $50 is awfully expensive for any pocket J-pole... unless if it was a patented design, built by Ed WB6IQN or one of his graduate students and personally tuned by Ed himself using a $20,000 test set. The antennas he has at Pacificon fly off the shelves every year. If you can find them cheaper I say go for it because it's way under-priced compared to the competition. Look him up, he will even speak at your next club meeting via Skype
