Default Antenna recommendation needed

On Tuesday, January 20, 2015 at 4:16:04 PM UTC-6,
Yes, because you are dealing with apples and oranges in the real
world, and until he comes back and describes what mode of operation
he prefers most of the time, I include both options.


What he prefers is irrelevant to a general discussion about how antennas
work.


This is not a general discussion about how antennas work.
Myself, I already know how antennas work.
These are replies to him asking for recommendations for antennas
to fit the room and lot he has. And what type of operation he
prefers to do is a large part of knowing the best antennas to
recommend, and is totally relevant.

He may well prefer DX, but on the other hand, he may well prefer
general rag chew type work closer in.
We haven't heard from him about that part yet, so I don't have a
clue on that part.


And I did NOT limit the discussion to verticals, I compared low mounted
horizontal antennas to vertical antennas.


I already know how low mounted horizontal antennas compare to verticals,
both by modeling, and many real world comparisons.
But this discussion is not about me, or what I may or may not know.

Good point. I'd forgot to specify that. I'm about fairly close to the
summit and the ground drops away mainly to the SSE with the coast about a
mile away. From here I can see couple of miles out to sea. Since I'm in
the centre of the British Isles, I'm in a great position for getting good
signals to and from South Africa - but not really anywhere else! :-(


What a beautiful part of the country! Many decades ago my parents
retired to live in a small village on the River Lune.

Pity about the take-off from your site :-( but the lower bands might be
well workable via a vertical. Use a horizontal for NVIS, and keep your
fingers crossed for some DX.

He specifically mentioned 40 and 20 meters and said he had a height
limition.

I compared low mounted horizontal antennas, which within the limitations
he mentioned would be low mounted, with vertical antennas.

That alone should be enough information for any half way intelligent
person to make some conclusions.

That is, given his stated limitations, for the lower bands, if NVIS
communications is the desire, a low mounted horizontal is called for.
If DX is the desire, a vertical is called for.

Just what specifically are you objecting to?

And I did NOT limit the discussion to verticals, I compared low mounted
horizontal antennas to vertical antennas.

Quite true; what was offered was general information for the original
poster.

I credit the original poster with having enough intelligence that given
some factual information with numbers he can make his own decision
about what is best for him.

Ok, understood.

Well, I have more than enough info to be going on with for the time being
so many thanks to all who contributed to this thread and assisted in
clarifying my choices very effectively!
