To All from PA0SE

This is certainly not naive Laurie.

I understand that in the LF aeronautical non directional beacons and ILS locators in our country such a series resistor is indeed included to avoid rain, snow and glazed frost detuning the aerial.

Hi All,

Perhaps this is just too naive-but would it not be possible to put a resistor in series to swamp the Ant.system resistance so that changes in it have little or at least less effect on the current! This would of course require more power to get the required current but for such a low power beacon this should not be too difficult. 73s Laurie.
