Here is a good one ..and ranged tested at 1 wavelength up ... #14 solid Wire.3" Aluminum Boom..24 feet. Starting from the reflector Reflector ..107.75" x 4 ...
Hola Erick, En el siguiente enlace tienes bastante información y medidas; http://www.ea1ddo.es/cubicas.html 73, Maximo - EA1DDO To: HAMQUADS@yahoogroups.com ...
don't build it.......i don't need any more competition chasing dx.........i can out work most pile ups now with my 3 ele 5 band quad over the 5 ele long johns...
It depends on how many loops you have got ie: reflector,driven and or director(s),a driven loop on it's own will be referenced over a dipole,but if parasectics...
I have a 4 element cubex 5 band up 21 meter. I want to put a optibeam ob2-40 (2 element 40m yagi) on top of it. I am wondering if any members have any...
Maybe, I missed the point of Barry's post. I was thinking of a single quad loop. Frankly, I'm not sure why in order to build a quad, we're referencing it to...
Hi all, You can put both booms together, the yagi inside the quad. 73, Maximo - EA1DDO To: HAMQUADS@yahoogroups.com From: funbiz@... Date: Fri, 27 Jan...
My advise is DON'T,you will destroy your nice radiation patterns from both,why not put a 2 ele 40 meter quad loops up instead of an inferior yagi.You say you...
No,you not missing the point Joe,you are very well correct,we shouldn't be using any of a yagi dimensions,but if you build a multi-loop quad,you should have a...
same difference it is true that quad loops can be configured in driven arrays, but generally they are used in parasitic arrays and speaking generally will ...
Well here's my 2 baht worth. Anything resonant on 40 within about a half wavelength on 40 (around 70 feet), will pretty much destroy whatever 15 metre...
Maybe I am wasting my time, but here goes: HF directive arrays fall in to two major categories: Driven arrays, in which the elements are fed from the...
Hi Everyone I have a 2 element lightningbolt quad I am going to replace it with a 4 element quad. My 2 element uses a 2:1 balum the lightningbolt book has the...
Bill, Is this a 3 band or 5 band quad? Or??? Is the 4 element quad as per the lightningbolt dimensions or a different arrangement? Wide spaced? In any case it...
Hi Bill, Usually four elements quads are designed for 50 OHm, so you only need a 1:1 balun or choke. Two elements quads are always around 100-150 OHm (112 OHm...

I took apart a Lightning Bolt matching transformer six months ago because I was curious. It wasn't a balun, it was a trifilar wound 2.25:1 unun. Barry N1EU...
I have a brand-new, never installed 2-element Lightning Bolt Quad that I plan to install, hopefully this Summer. I sold the multiband matching transformer...
Try using the Budwig Center Insulator. All you have to do is connect the wires to the Budwig and plug in your pl259. W5RY From: HAMQUADS@yahoogroups.com...
Thanks for the suggestions, everyone. I do have some of the Budwig center insulators, which I picked up at an estate sale. They would be okay if I was using...
Larry, Look here, about halfway down the page. This is what John did and I have some I made to use here that are identical and I made them from 1/4 inch nylon...
I plan on using the budwig. I will use a couple of the copper wire nuts, the ones with the split bolt and nut, you use for connecting 10 and 12 ga wire. W5RY...
Hi All Thanks to all that answered my post. I planed to make it just like the 4 element lightningbolt. Some have suggested to feed with separate feed lines...
