	That all depends how legal you are.  My 1 watt 180 kHz beacon working
into a 50 foot tower with lousy ground resistance runs about 200 ma RF
under the best of conditions.  Of course, if I push the power so goes
the current.  I'd think a 1 amp and a 4 amp should meet all your needs. 
I have TC meters from    100 ma FS to 20 amp FS and have used them all
for something at one time or another.  Neat gadgets BUT THEY WON'T TAKE
MUCH OVERLOAD!!!!!!!
