I think you will find that you need to remove the 300 footer before trying
the low height antenna- otherwise mutual coupling effects will surely stuff
And at 300 feet you will be getting out of 'very short vertical' territory
anyway, even on 136.

The possibility of transmitting from an ex Decca site is very intresting I
would like to put foreward a suggestion for an experiment.Theory has it that
the radiation pattern for a much shortened vertical is not dependant on
height! Some on this reflector disagree.Would it be possible to radiate say
1w erp from the 300 foot antenna and the same power from a co-sited very
short vert similar to those being used by many people, if they used the same
ground system all the better.Then by transmitting alternately from each
station we could gather signal reports from many recieving stations both
near and far,for various times of the day.
Perhaps then we could settle this argument once and for all.. 73s Laurie.
