You've received some great suggestions, Jeff.
I like K1WJ's idea of making an antenna base support
with a bucket and quick dry cement. Lowes & Home Depot
sell 5 gallon plastic utility buckets for less than $3 sometimes.
They are "loss leaders" to bring people into the store,
but they are good and useful products. I have 3-4 of them.
But I would change one thing about WJ's suggestion:
Instead of a wooden dowel, consider sinking a pipe in
the middle. The inside diameter of which would be slightly
larger than the O.D. of your antenna mast. That way you can
move it around more easily. (The pipe would be sticking only
about 4" or so above the cement.)
ALSO: You could use such a base outside when you go outside
or "Hill Topping". This is fun. Look on a map and find some
mountain or hill you can drive to the top of. Take your rig,
antenna, and coax out there. Radio is powered by your
car battery. Setup the antenna base, then maybe a 10" (or
longer) piece of PVC pipe and get your antenna up in the air.
We're havin' some fun now!
An alternative, though a bit more expensive way to get a heavy
antenna base is to buy a plain cement "Patio Umbrella Base" from
a hardware store. I have two that I use to hold up 15' fiberglass
telescoping poles, which in turn hold up the ends of my 80m
Inverted Vee. They are about 24" in diameter, 6" high, and have a
thick metal pipe with an ID of about 1.25" with two wing screws.
They weigh about 25-30 pounds and (when I bought them)
cost about $25 each. I tried to find you a link but I couldn't.
(didn't spend much time, I must admit it was a quick search.)But I'm sure they still make them.
I only found the more
expensive iron or fiberglass filled-with-sand ones.
The plain cement patio umbrella stands will support a
suprising amount of weight. I live in a very windy area and
have had no problems with mine supporting pretty tall
poles and wire antenna. Also, seeing that you live in an
apartment, you wouldn't have to go through finding a place
to mix the concrete or to worry about making a mess in the
apartment complex parking area. Apartment managers are
pretty nit picky about those things. Still, the bucket/cement/pipe
idea is a pretty nifty and money saving idea.
Re the power supply: I think the Astron 35M is over doing it.
I am not saying that it a poor product, it is a great product.
You don't need 35 amps and you don't need the meters.
I think the 23 amp Samlex 1223 is a good value and is
compact and unobtrusive. You don't need it's 23 Amps
either, but it is only $15 more than their 12 Amp model.
Plus it will power a 100w HF rig when you move up! http://www.universal-radio.com/catalog/hamps/3747.html
OK, enuf outta me.
Good luck and welcome to ham radio.

PS: You mentioned "putting the antenna in a corner of
my apartment". Can you put it in front of a big picture
window? Or any other window? With the blinds closed?
