My Home Brew Cubical Quad+1 antenna 5 element made back in feb 11 1999
The spacing of each element is tuned for freq length.
and all 3 directors are the same size.
the driven of course is the Second one from the back from the center point of the mast..
I know its only 1 picture and hard to see the cubed copper around the elements..
The outer part of the elements were made red/orange 8 foot from garden stakes.
I guess they were some kinda of heavy duty fiber plastic,they worked at the time.
The boom was 1 1/2 inch round and was 34.5 foot long and a bear to work with.
each element was spaced almost 7 foot apart from each other give or take a few inches for fine tuning..
the reflector element whole length was 34 foot, and for the rest of the elements,Driven,director 1,2,3 take about 1 foot off going down to director 1 ,which is the front of the quad beam..
now in order to keep the SWR low this antenna didn't have a matcher it was the length of the outer cubed copper wire.
put it this way just the wire on 1 side of the cube was 113.5 ,inches(9foot 5inches) so taking standard coax,black RG58 50ohm unbalanced and ataching it to the balanced corner of the
driven wasn't bad seeing though I did the math and made the quad centered for 27.2050(good old channel 20) my SWR was at 1.2 which wasnt bad..
The worst part about this whole thing..and i mean in a bad way
I did this all myself, besides having a buddy stretch out the 200 foot of copper wire with me with his truck and a eye ring mounted to the side of a barn...
the second worst part was keeping the copper straight well making the 9.5 foot bends for the cube!
I never did see how heavy this thing was but it was a bitch putting it up for a 1 person job..it was up for about 3 years before it got sold.
That 100watt box I was talking out of had no problem talking anywhere I swung that quad to as you know the gain on any beam is sweet!
The rejection..well the hole backside of the antenna was one..
a good friend 5 miles from me had no problem watching me go from 30+ to about 1 on his meter when i swung that sucker away from him...
it was under 100 bucks to build ..less rotor that was 300 bucks with a bearing.. I had that rotor untill 1 week ago with a bearing
some MotherF$%#er stole it off my porch..1999-2007 RIP rotor
Thanks for looking
Until next time when lords puts up his Spitfire 427 3 element beam
with a 25 foot Reflector for starters..
