I would expect Z to be higher on 60MHz then on 1.8 MHz.
With the outside diameter of 5mm for RG58 40 turns would require a coil
length of at least 200mm ~ 8".

Myself, I am using a air wound coil, 40 turns of RG58 on a 4 1/2" D, 6" L
cylinder as the choke. No, it is not hanging in free air but is well
supported. End up to work well from 1.8 to 60 MHz. Has a Z=500 Ohm at 1.8
MHz and 60 MHz.
