Rick, My quote was "the same 7 MHz capability as a C4" Remember, that is a separately fed 40 meter rotatable dipole. 73, ... Joe, K4IK _______________________________________________ See: http://www.

I used 3/16" EHS years ago at the AD8I multi-single station in the Columbus, OH area. Worked just fine for everything we needed, including a KLM 4L40. 3/16" EHS, a 2" U-bolt on the mast above the mou

On 40 meters, a rotary dipole at 45' will beat a ground mounted quarter wave vertical and a dipole at 30' will beat the vertical over very good ground for take off angles above 15 degrees. If the gr
It might be possible to substitute a MonstIR DE into the 3L yagi (20-6) but the 22:50 Ohm un-un would be a problem on 40 and 30 meters. Mike and Jim would need to design a relay switching arrangemen
That depends on what you mean by "5 won't work much better than 4." If you are talking forward gain, you're correct - gain is proportional to boom length. If you're talking about maintaining gain ov
If you are going to do that, keep the beans pointed between 45 and 135 degrees to each other ... the closer to 90 degrees the better. The coupling between antennas will be minimum at 90 degrees but
If you do some investigating, most building codes specify "fastest mile" wind speeds (UBC-97, RS-222-C, etc.) see: http://k7nv.com/notebook/topics/windload.html What standard are Dade and Broward co
All true ... however, if one is using 75 Ohm cable in a 50 Ohm system (e.g., CATV hardline) then the multiple of 1/2 wavelength shows a 1:1 SWR on a 50 Ohm bridge - exactly what is desired. The 75 O
The Wilson DB54 was a dual band 20/15 (5 el/4 el) antenna. As I recall the 20 meter elements were fairly evenly spaced to provide "room" for the 15 meter elements. As I recall, the Wilson antennas a
As I recall, the N6BV path data is a compilation of all angles over the entire solar cycle and were generated with isotropic radiation (with gain) on both ends. Those angles with higher probability

Morel, Of course they are. If you spend a little time working with the modeling programs (or reading the ARRL Antenna Book), you will find peak F/R is relatively narrow on most yagi designs and most
"Slightly" is most certainly the right word. If one were designing for > 20 dB F/R on 10 meters, a four element antenna would have a 24 to 26 foot boom. The four element SteppIR uses a 32 foot boom
Actually, the boom is too long to provide high F/R on 10 meters, not too short. F/R on 10 drops into the 10 to 15 dB range which is more than enough for most people (and as good as the measured F/R
