SteppIR to be a commercially feasible product. The current and future SteppIR products should produce the most potent single tower antenna systems ever seen in Amateur Radio! We thank you for using our SteppIR antenna for your ham radio endeavors. -
Page 4: Steppir Design
Currently, most multi-band antennas use traps, log cells or interlaced elements as a means to cover several fre- quency bands. All of these methods have one thing in common–they significantly compromise performance. The SteppIR™ antenna system is our answer to the problem. Resonant antennas must be made a specific length to operate optimally on a given frequency. -

Page 25: Using A Vertical In Or On Salt Water
When using a small metal float (3 ft x 3 ft is just enough to “connect” to salt water), you want to be certain that the metal does not corrode over time. For long term immersion, Monel is a good (but fairly expensive ) choice. 2112 116TH AVE NE SUITE 1-5, BELLEVUE WA, 98004 WWW.STEPPIR.COM TEL: (425)-453-1910 FAX: (425)-462-4415... -
