Default 6M stacked loops - best height above ground?

Hi Charlie

I have read some of the responses you have received already. As you
asked for first hand experience I hadnt commented initially.

I wonder if you have tried modelling your configuration with height
variables and applying the resultant radiation pattern to propagation
modes? I'd suggest ground conditions for your area also need to be
entered. I seem to remember from my dim dark past that ground
reflections (and hence undesirable skyward radiation - often not usually
an issue on VHF) are more of a problem when using a lower gain antenna.
Maybe the loop in that respect might be worse than a quad/yagi?

You'd be able to see the dB per foot height changes that occur and make
a judgement from that.

I have never used horiz loops on 6m.
