Default one and a half meter US amateur band: antennas for 225Mhz, or CH 12-DAB ..

I have a Digital radio and reception of one packet on 225Mhz is poor.

This sentence gives me hope:

"DAB is very close to an American (not European) amateur radio band (the
220-225 MHz or one and a half meter band). It is therefore possible to
find suitable instructions for building an own aerial in American
amateur radio publications".

Anybody can point me to such a publication??

I have a general band III TV antenna, designed for 170-240Mhz,
but the station is on 225Mhz, so thats on the upper side of the
band. I already "redesigned" a yagi antenna and made the
directors closer to each other, but do not know the exact size,
or maybe there is some simple design that makes the signal boom.

Is there a publication/calculation to design Yagi's?

(I built a loop for ~500-1850khz and I'm dreaming of a loop antenna ;-)

Thanks,

Marc
