I’m considering putting up an LPDA this summer to augment the existing stuff.
The LPDA would serve two purposes:
1. 30m/17m/12m DX chasing. I suppose that really means 30/17 as I can’t
remember the last really solid 12m opening...
2. Fixed-on-SA for 20/15/10m when contesting.
The problem is the usual tools for helping on height (HFTA) are more or less
band specific so what is the best height on (for example 20m into SA) is not
really a great height for another equally important (e.g. 30m DX into eastern
side of EU). In playing around with HFTA clearly each height seems to provide
some benefit over another. Higher band and higher height gives more nulls but
better low angle performance.
I figured that something around 80-100’ overall but would greatly appreciate
any suggestions...
