Hi Mark
Put down as many non resonant ground or elevated radials as you can. You can do nothing about the far field pseudo Brewster angle. The Hi Z manual states the recommended deviation in element elevation but I suspect it will work OK. 73  GL

I am preparing to relocate to the western part of NC.  Mountains (well, hills compared to Western USA).  I understand the importance of propagation and terrain, and I have been following Rich/KY6R and his adventures.  I have also looked at HFTA for more info.

My question is this: the soil will be less conductive at my new QTH.  But what about the near field reflections and pseudo-brewster angle?  Sure, there's nothing I can do about that...just try to put down some radials to minimize near-field loss.  But what can I reasonably expect?  What have others experienced/attempted and achieved success with?  I am looking to save myself some time and frustration by avoiding those approaches which will produce less-than-optimum results.

I am thinking elevated radials for the inverted L, due to poor soil conditions.  Should I run those at two per band if I want to use the inverted L as multi-band?  How should I orient them?  How do I prevent common-mode coming back through the remote coupler?

Will the HiZ array be useful?  What if it's not located on perfectly flat terrain?

Thanks in advance.
