Grogs,
I think the divider alone might work (scrub the 1k) but you might be better off with just the 1k direct from the 5V RF output to Pin26.
If you were really concerned clamp pin26 with a diode that has the ANODE at pin 26 and the CATHODE at Vcc using a 1N5817 (or IN5819) SCHOTTKY diode.
Kind Regards,
Mick
