I'd be suspect. The X500HNA ("heavy duty") is only rated for 200 watts. I've
never pulled the guts out of an X500HNA and an X510 and laid them down side by
side so I can't comment on why one is rated at 200 watts on both bands and the
other is rated for 330W/250W. The small ceramic disc capacitors they use would
likely be the weakest link as far as power handling goes.
A little Googling reveals that X510NA or MA (type N and UHF respectively) are
rated for 200 watts, but the X510HDN or X510HDM are rated for 330/250 watts.
Unknown what the differences is between the two other than the specs...?
