Hi Tony,
It all will depend on the height of yor planned antennas.
As long they will not produce useful low angle radiation below 6° those 5.8°
degrees will do no harm anyway.
Best is to simulate it with HFTA, for some dx distances you really need very
low angles.
In some directions my horizon is blocked at 4-5°, except on 10m none of my
antennas radiates that low with their main lobe, but there I still have a
bit of gain at 2° and get through to dx worse then other stations behind
those hills.
On 2m and higher those directions are really poor to work.

Subject: [CQ-Contest] Angle of received signal QUERY
I am trying to determine what would be the lowest angle from which one could
expect to receive DX signals? It seems that at one time I read 5 degrees
but I've done some research and can't find the answer so far.
I am looking at a QTH here in Colombia that in one important direction has a
hill about 330' higher than would be my antenna. That hill is 1KM or 3,250'
away from the antenna.
Using right triangle calculations the angle between my antenna and the top
of the hill would be about 5.8 degrees. I'm concerned that the hill would
have some affect on
long haul signal reception. Should I be concerned???? Otherwise the
location is
fabulous.
