Good day, I'm certain there are many out there with much more experience with antennas than I. One day soon I will get my new 80 foot crank up tower. Not to waste a good opportunity, I was planning on making the four guy wires antennas too. Just makes sense. On top of my tower will be my CushCraft MA-5B. I was thinking of making the four guy wires into 40 meter vertical antennas and then I had to stop there. I can see one 40m inverted "V" but two? I already have a six pos remote coax SW! #1 Whats the value of two inverted Vee's 90 degrees offset from each other?? #2 Isn't the pattern for an inverted "V" on a metal mast about omni? #3 A long time ago in a galaxy far away I had a Super Scanner antenna. Anyone remember those? It was for 11 meters but many have been reworked for 10m. As I recall, the hot dipole used the other two cold ones and you got a three quadrant "beam" of sorts. #4 Any way to create that type of effect using 4 40 meter slopers? Or maybe three? Thanks in advance and wish me luck! 73 Dave K6NYB |

Switching between Inverted Vees can give you a few more dB of gain, a worthwhile improvement on HF.

Though the dipole in this array may not be exactly vertical, the signal i Zack Lau W1VT ARRL Senior Lab Engineer |

Why not configure two quad loops instead of two vees? more gain, more bandwidth for coaxial feed. |
