There is an 8in antenna option... also note the question comes from Canada and not the USA.
SAF certainly offers it... and it meets the gain and beamwidth requirements below (3.3 degree beamwidth, and 33dBi gain antenna).

It doesn't have to go very far, but we are wanting 24GHz. It may be a problem because the FCC rules for that band are pretty strict. From 15.249: (3) Antenna gain must be at least 33 dBi. Alternatively, the main lobe beamwidth must not exceed 3.5 degrees. The beamwidth limit shall apply to both the azimuth and elevation planes. At antenna gains over 33 dBi or beamwidths narrower than 3.5 degrees, power must be reduced to ensure that the field strength does not exceed 2500 millivolts/meter. So you can't get much smaller than a foot an still stay within the 3.5 degree beamwidth, at least using oonventional dishes. (To be sure, I haven't done or seen a computation of exactly how big a dish that would be, or what alternative shapes would do, but I assume that the uniformity of 24 GHz antennas is based on that rule.) -- Fred R.
