I am very interested in building this multi band vertical as printed in ARRL's
“Simple and Fun Antennas” titled "WA5ABR's Homebrew Seven Band Vertical.
It is a multiband vertical with parallel feed (only one coax feeding all elements), using aluminum elements and plexiglass to "support" and seperate the seperate vertical elements.
I own a 259 Antenna Analyzer.
If you have not built this, what do you think of it?
Has anyone built this antenna? If so:
1. Are you still using yours?
2. Any problems with interactions between the vertical elements?
3. I was also considering using two or more separate feedlines, I have
read where this would reduce interactions.
4. Mainly I am interested in 40, 20. 15 and 10. For 40, I would either
have 25 ft vertical and capacitive top loading (prob about 4 ft diameter top
hat) OR use a full sized vertical element.
5. I am also considering adding 75 by using somewhere between 25 and 35 ft
vertical and the rest of the 75 meter wire horizontal (inverted L).
7. How about adding a vertical element for 6 meters?
I am an older ham who is trying to get back up on the air. The city I live
in, Aurora, CO, does not have any inspections or requirements for antennas 25 ft
and under. For anything over that, a Colorado certified Engineer must sign off
on antenna plans, and 35 ft high is the max.
I also own a cabin in the CO mtns and need an antenna there. Restrictions
there are much easier but there is still a county limit of 35 ft. I have a
neighbor up there who has all ready sent me a nastygram Email and I don’t even
have anything up at cabin yet. I have an HOA there but no antenna
restrictions. I have a thread on both QRZ’s Antenna and Eham’s forums on
