At this point the bottom cone and the top disc should be complete

Screw the pvc threaded bushing to the top flange, Place the copper disc on the top copper wire Solder and cut this wire, Fit the cap and bushing Attach the flex pipes to the cap epoxy the cap bushing and flex pipe together

*once you are sure everything is right, you may want to fill the gap between the flanges for weather proofing

Mast mounting

Depending on the thickness of your mast you will need to adapt the bottom flange diameter with a bushing

Feed the rest of the coax cable down the mast pole Screw the cable up to the bottom connector in the antenna flange Twist the antenna onto the mast

I use two 15 foot lengths of well pipe threaded 1 inch with one end driven three feet into the ground with cement filler. Then with two riser bars I can adjust the height of one pipe against the other to raise and lower my antenna. Since the mast runs through the bottom of my elevated deck horizontal swaying is accounted for. If its a free standing mast you need to anchor rods into the ground and run guy wire depending on your situation I would seek advice.

Grounding

Grounding is very important, a whole other topic in itself. It depends on your individual situation, however i will share what I did for mine.

At the bottom of the pipe (where the coax cable feeds out of) I have a grounding clamp on the mast with an 8 gauge stranded wire going to my ground rod. the coax itself is then attached to a surge arrestor with the ground wire of this going to the rod with a 10 gauge stranded wire

Both wires then attach to an inter-system bonding clamp with a 30 foot 4 gauge aluminum wire (always use cu to au connectors) feeding back to my main panel neutral/ground. this is important to bond these two right when you use a separate rod, its strongly advised to mount the giant antenna on the other side of your house away from the incoming power line for obvious reasons!

Final thoughts

My design omits a bottom support for the radials, I'm probably going to create a revision to this that might include another set of flanges and a cross support to hold them up as they look terribly bent right now. The performance doesn't seem to suffer too much but I'm planning to do it none the less.

So far I've been able to pickup clear signals from 25mhz to about 900mhz. My dongle caps out at 1.7ghz and i think i saw a few signals from cellphones up there but nothing remarkable.

I hope I was clear enough with my instructable and this helps someone out there. This is the first time I've completed one so give me some feedback!
