Dear WA1RKT:
For less than $1000 you may purchase and use a LPDA that will accomplish what you specify. Several such antennas are on the market or you could construct one from scratch. Some positive aspects of a LPDA: 1. no moving parts 2. "instant" BW so you may use the scanning you mentioned 3. using anything that is at all of a reasonable size, the antenna inherently has low sensitivity to minor construction and other errors (much favored in ice country because their performance degrades slowly with ice coverage - not found to be true with a critically "tuned" yagi) 4. performance as constructed is close to that predicted with NEC - tweaking is usually just not needed (occasionally, the shorting strap needs to be tweaked) Consider the conventional solution for the BW requirements you have set out. The StepR antennas work, but questions remain as to how well and for how long. If I were to go on a trip to a salt-water DX entity, I sure would use their vertical right on the beach. In other words, they are a solution to some problems. Good luck. 73, Mac N8TT -- J. Mc Laughlin; Michigan U.S.A.
