They will need to be different lengths than the 2m radio.

The 70cm/440 radio will need a tail to be about 6 1/2 inches long.

Beetle; what is the 1/4 wave length for the 220mhz band?
Can't recall right now - ATM.

So, find the formula that is used to determine one wavelength at ~220mhz; and then divide by 4. Done.
