Here are some pictures of my homebrew 2m antenna.
It's a J-beam: J-pole with director and reflector.
Captured the idea from N3SDO (more details on:www.dxzone.com)
The bandwidth is far not as wide as that of the standard jpole by itself and SWR tends to rise faster (calculated for 145Mhz and having an 1.4 SWR in that range). I estimate getting an 6-7dB gain and 20 dB F/B (front to back ratio).

Red circle is pattern of standard omni J Pole
blue area is estimated pattern of JBEAM
