I have an idea for a house that will probably never happen, but I would
like to have the group's ideas on it anyway. This will be fun.

You have a piece of city property that you managed to acquire that was
200 by 200 feet. The lot is somewhat sandy and also is whatever fill
the contractor found.

The city allows a 60 foot tower with no permit required.

You are going to build a house on this lot. Fresh design. Especially
including the

How do you build the house so that it will allow all bands on HF to work
as well as possible?

How do you build the house so that it will allow VHF/UHF handheld
communications to work as well as possible from inside the house?

At the same time, how do you meet exposure requirements for the inhabitants.

Living in a small tent rather than a house would maximize the room
available for HF antennas, and be great for VHF/UHF communications from
inside. Best to put the tent at a corner of the lot.

60 Ft commercial tripod tower strong enough to serve as support for a
3rd Story round apartment between the legs. In my dream, the apartment
is on a hill overlooking the city.

How about making all rooms 20'x20' and stacking them with a slightly larger
garage as the ground floor. With the currently popular 10' ceilings, a 3
bedroom, 2 bath house with a den and dining room would bring your roofline
to approx. 90 feet. I think one could work wonders with the den/shack as the
upper room, especially with a "widows walk porch" going all the way around
it. (G) Am only half kidding with this design.

I'd say build a 20 story hotel on the property with a parking garage
in the basement, a great restaurant, a penthouse suite with a view to
live in and operate from, and an HF log periodic up on the roof. ;-)

Logs are Passe'; Use a SteppIR.
Otherwise, spot on, you even make a profit on the whole thing.

Close but No CIGAR!

Yep! Build the hotel. Sell it to Donald Trump. Buy an Island in the subtropical
Pacific.

Move to the Island.

Then do whatever you want for antennas, power levels, exposure limits, get a
good QSL Manager who will never bother you, etc.

But, leave some time for fishing, bikini watching, and brew enjoying. If you
plan it correctly you can get a VERY RARE KH8 license ...

Hmmm ... I don't like pile ups. Oh well!

I see the gain figures on that beauty and I puzzle over why the dBd and dBi
gain figures are so far apart -- about 7 db. I expect a difference
somewhere in the 2 - 3 dB range. IIRC it's 2.2 dB. What am I missing?

Before I sent this, I did a Google search using some of these terms and
discovered "ground reflection gain," a term I have never seen before, except
in connection with EME with the moon near the horizon. Is this a realizable
gain or damnable inflation of gain numbers?

TKS.

Yep. Put a 1/2-wave dipole 1/2-wavelength over sea water and compare
its gain to the gain to a isotropic in free space.

Actually, the gain of a horizontal antenna at reasonable height and
reasonably low angles is nearly the same over plain ground as it is sea
water.

But do what Danny says, and you'll find that a dipole over ground has a
gain of around 6 - 8 dBi. While dBi is rigorously defined, "dBd" isn't.
Using a common conversion of 0 dBd = 2.15 dBi (the gain of a dipole in
free space), you find that a dipole over ground has a gain of about 4 -
6 dBd. At least one major antenna manufacturer quoted the gains of their
antennas over ground in "dBd". Naive people assume that it means
"compared to a dipole at the same height", while it actually means
"compared to a dipole in free space". Gives their antennas an instant 4
- 6 or so dB boost over the competition.

BOTH!!

Ground reflections CAN add to the 'freespace' gain at certain antenna heights
and angles of incidence. The ground reflected wave is is phase with the incident
wave.

'damnable inflation' ... well if one manufacturer uses the term in it's
marketing literature then the competitors will follow. Then 'gain' comparisons
go to H..L!

The best comparison is free space gain [calculated] as dBi or dBd.

I used to mamange a microwave antenna test range. Out antennas were installed
between 20 to 30 wavelengths above ground to reduce 'ground effect confusion'.
