This graph compares the effective parallel resistance, parallel inductive reactance and the magnitude of the parallel impedance of a W8JI (conventional) and an AG6K (nichrome wire) suppressor.

As the chart shows, at VHF, there are only slight differences between the effective parameter values for the two types of networks. A comparison of network Q shows this more clearly. Some mathematical manipulation can demonstrate that shunting the conventional suppressor with an additional resistor will bring the curves into better alignment. An additional 250 ohm resistor in parallel with the network will cause the Rp curves to nearly overlap the nichrome curves above about 30 MHz. Below 30 MHz, the Rp of the adjusted conventional type will be higher than the Rp of the nichrome device. If a parasitic suppressor functions as described by conventional wisdom, then this should be a more desirable case.
