|I wish to know how could I build non-inductive 600-800 Ohm 1KW resistors
to use with rhombic antennas.

Instead of high value high wattage resistors that are probably hard to
find and expensive, how about using a 12:1 or 16:1 broad band transformer
and putting a regular high wattage 50 ohm dummy load on the low Z side.
I used to drive an HF point to point transmitting station ( Falklands -
UK) which used three nested 1100 foot long two wire rhombics at 110 - 150
feet high. Those beasts had open wire feeder from the out end to ground
level, terminating in big ventilated termination boxes enclosing a bunch
of high wattage carbon tube resistors in spring clips.
