The fault was mine, not Roy`s. It is true that if you scale an antenna
for half the frequency by doubling its length without increasing
cross-section of the wire, its resistance increases. Resistance is
rho(l/a) where rho is the resistivity, l is the length of the wire, and
a is the area of the wire`s cross-section.

Roy noted that lowering frequency by half means a wire twice as long
which tends to double the wire`s resistance but skin effect increases
penetration of the wire at the lower frequency. This reduces resistance
by 1/sq.Rt.2. The same antenna using twice the length of the same wire
but at half the frequency thus will have 1.414 times the effective
resistance of the double frequency antenna.
