[Elecraft] KX1 built in dummy load

[mc]

Since the KX1 is power limited I would like to build a dummy load and attach it to the side of the unit. If I take a short piece of coax and use a 5 watt wire wound 50 ohm resistor  dip the end of the coax and the resistor in plastic vinyl the kind used for insulation tools handles, would the close proximity of the dummy load cause undue heat  or other problems.
