An ingenious design for working multiple bands without a tuner. You gotta see this!
http://www.yf1ar.com/2011/10/remote-tuned-dipole-that-covers-all-of.html
10/11 Meter 4 Element Hybrid Moxon Rectangle
Materials:
3/ 10 foot lengths of 1/2" schedule 40 electrical conduit
13 fiberglass rods or 6 non conductive poles for each end of spreaders
2 mm/12awg bare copper wire solid
zip ties
nylon chord
duct tape
6 u bolts
6 SS hose clamps (smallest you can find)
This build provides awesome gain (almost twice that of a standard 2 element moxon) as well as great bandwidth.
So far during Sporadic E conditions this summer, stations report my signal 1.5-2 s-units hotter than what I'm receiving from them running 2 to 3 times the power. This has been regardless of polarization on receiving stations. It will be interesting to see how well it does when or "if" the band reopens to 3-6k mile propagation in the fall.This design serves a valuable purpose for those like myself who live in a deep hole. Notice the strong 3 main lobes in the elevation pattern.
SWR's 1.3:1@ 26.500mhz, 1.02:1 @ 27.500mhz & 1.3:1 @ 28.900mhz
Resonance : 27.555mhz

2 Element Yagi for Static Mobile DX
Chucks Moxon Build 2OR208 CA
11 Meter Moxon Antenna
Tune Frequency 27.415
Material List
1. Small section of tubing to mount antenna to
2. Two Muffler clamps for the size tubing you use for the mount
3. 1-4' section of 1"Aluminum Tubing
4. 4- 5/8" fiberglass plant stakes 5' in length ( I cut mine to 52"and drilled down the middle 4" to accept driveway markers)
5. 4-4'driway markers
6. 8 hose clamps (4 the smallest size to go over end of plant stakes, 4 next size bigger to fit over aluminum tubing.)
7. 4 small washers i used plastic one that are non conductive metal will probably work also.
8. Plastic wire ties some large and some small ( i used large ones for the gap between reflector and driver ends.
9. Non conductive plate to mount driver wires to.
10. 50 feet of 14 AWG insulated wire
Small section of tubing with aluminum tubing mounted with muffler clamps.
Fiberglass plant stakes drilled with driveway makers installed. The hose clamps are used to help strengthen the ends of plant stakes. Also i cut slit in the aluminum tubing so i could clamp the plant stakes to keep from rotating.
A piece of plexiglass non conductive to mount driver wires to. One wire goes to the center of the coax the
other to the outside sheet.
I used a short piece of pvc pipe to hold the coax up to keep it level with the ends.
this is where i used the small washers to attach the wire to the driveway markers. I used small wire ties to keep the wire from moving.
The measurements below are for a moxon with center tuning at 27.415.
A= 149 5/8"
B= 22 1/2"
C= 4 1/8"
D= 22 15/16"
E= 54 5/8"
If you would like the moxon tuned for a different frequency, you will need to consult the moxon calculator by going here-http://www.moxonantennaproject.com/design.htm.
