A Ground Plane antenna project for 10 meters band by N4ZAW.
SWR is under 2:1 from 26.960MHz to 29.890MHz. Reports are excellent. Sure, its ugly. But it is paid for. Pay no attention to the wire going-off horizontally from the base.
It’s just one end of my G5RV dipole, or sometimes called a “dummy load” (sorry — just an old ham joke, hi hi). Actually, I’ve made hundereds of DX contacts on that piece of wire!
The link for calculations used and LOTS of kewl ideas are found on“THE ANTENNA ELMER”
PartsÂ Sources and Prices of materials used:
Large (1inch to 3inch size heatshrink Tubing available only one place that I know of, that being “Parts Express”.The cost depends upon the diameters,with the entire cost for what I used to weatherproof my antenna at around $15.00. Add a couple sticks of hot glue for sealing. 4FT of 1″x1/8″ aluminum bar stock from lowes($15.00)“MIGHTY PUTTY” Cost $10.00 for three sticks….One telescoping “pool pole fromBJ’S Wholesale Club , (sort of a Costco,or wholesale wally word) Price $16.00
The 10’3″ fiberglass poles were purchased (5buks each) at ALLWATERS FISHING…
I used #12 solid copper, but #14 stranded works just as well, except for the top hat. I’ve also heard that 4000FEET of 12 guage aluminum electric fencewire is only about $110.00 fromTractor Supply stores.If this is true, my next project may be a Rhombic for 160METERS :)Another great online source for wire is“The Wire MAN”out of SC.

- 1 pack: (8 ea) 1/2 conduit clips
- 1 12″ piece of 1.25″sced 40 PVC pipe for insulator section.
- 1 12″ piece of 2″ PVC electrical conduit (fits nicely outside of the 1.25″PVC for super strength).
- 44Feet: #14,16, or 18 copper wire for ground radials(make sure at least2 feet is solid for coil).
- 21.2 Feet: tubing, preferably aluminum, but whatcha got? Can be telescoping (one section inside another).
