 Folks  de  K5DEJ

Is there a formula for determining the radial length, i.e. other than 468/f
MHz ???   I am trying to get a High Sierra 1800 Pro to resonate on my Motor
Home and have not been successful, as of this writing.
    
I have searched the books I have here in the shack on the subject of radial
length but have not found anything other than the radial length should be
approximately a quarter wave length.  I have cut the radials I have used to
the lengths specified by the above formula but have  not been successful in
getting the 1800 Pro to resonate. 

I would like the antenna to cover the frequencies of 4.025 MHz (MARS), and
40, 20, 17, 15, 12, 10 Meter Bands with a low SWR.  The 1800 Pro is mounted
on the back of a 28 foot Class C Motor Home.  Radials will have to be routed
to use the available space on top of the motor home.


Any assistance would be greatly appreciated.


 Peace and all good
