| Would you seriously consider using 27mHz for anything other than a cheap
Well, the danger with 27 mhz has always been CB and people with R/C
toys. The CB threat has diminished somewhat -- it's probably on par
with the pager menace in 72 mhz now, but the kids with their cars are
still a danger.
Still, there's quite a bit of R/C stuff on 27 mhz out there.
| And, when was the last time you say an RC system on 49mHz
All the time, actually. The permitted power is limited, but there's
lots of R/C stuff on 49 mhz. Mostly things that don't fly (cars,
boats, robots, etc.), but some planes.
| 900mHz 2.4gHz or 5.8gHz?
The poster asked for a sutiable frequency. I don't know about South
Africa, but I pointed out that the US has them.
Of course, one could just argue that the US isn't civilized.
Certainly, it's been done before ...
| I was only referring to realistic expectations.
27 mhz is perfectly realistic for US use. 49 mhz limits your power
too much for many uses, and for the other bands (except for the ham
50/53 mhz ham bands) you'd probably have to make your own equipment.
If you want something you can legally for both ground and air use, and
you don't have a ham radio license (easy to get), and you're in the
US, 27 mhz is probably your best bet. Of course, the risk of
interference is probably higher than in the 72 mhz band ...
Of course, he was asking about South Africa ... obviously neither one
of us knows what frequencies they have available.
(Of course, *any*
frequency that permits ground vehicles *at all*
might be considered unsutiable by you. Even the ham bands. But which
is worse -- to be shot down by some kid with his new R/C car on 27
mhz, or to be shot down by somebody setting up his new R/C park flier
on 72 mhz? Or shot down by somebody with an R/C boat on 72 mhz, using
equipment salvaged from a plane? Or, using the ham bands, shot down
by somebody pumping out 1500 watts in the next city? Ultimately, any
time you go up, you run the risk of getting shot down ...)
