Low range

Hi there

i've build one of those Skew Planar Wheel for my 910Mhz 800mw Hobbyking RX/TX Set but the result is extremely bad.

Though i tried to keep tolerances as small as somehow possible (<= 1-2mm) it does not give me more than 200m of range in direct line of sight. Tried all channels 1-4 (910-1040 MhZ) and channel 3 ist best. The Standard antennas even give me slighly more range and more robust signal. Any Idea what might be wrong?

Here's a pic of my two antennas:


P.S: 900M Mhz is the primary band for cellphones right over here. Might this affect the range that much? Cellphones are allowed to send 2W .... basestations about 8W.
