I just did some calculations from the ARRL Antenna Handbook. I came up with a 6-turn helical with a diameter of 25.826" and a length of 121.65". My first thought was "whoa, dude, like OMG!" (I'm a high school teacher, ok?) I rechecked my calculations and came up with same, plus an impedance of 150 ohms.
Years ago I used a Fritzel Helical for 2m when I was DA1BB and VP2EHF (during Hurricane Luis in 1994 it ended up someplace out in the Anagada Straights between Anguilla and Sombrero Island).
What say, you all? Advice, comments welcomed
