10m Bent attic Yagi by KE4UYP
This is a horzontally polarized three Element Yagi. The bent Elements cause very little performance lose.
When you consider it is only 8ft. 5" wide and 7ft. 6" long and still has 6.2dbi gain and 20db front to back ratio.

A Simple Nondirectional Antenna for Ten Meters by W7AYB
There are several reasons why a ham whose chief interest lies in the ten-meter band may not want to or cannotput up a rotatable beam. Such an antenna is expensive, it requires a sturdy support, many consider it an eyesore, ...

The 10 Meter Loop Antenna by KGØZZ
Loop antennas are a favorite among hams. They are a simple design and offer more gain than a half wave dipole antenna. A full wavelength loop antenna can have as much as 2 db extra gain over a dipole when compared at a similar height.
