Hi, all.

Well, I have been bending the ear of Kevin (K7RX) off list on this topic, 
and thought I'd seek input from others here on the list about an antenna 
dilemma I'm having when considering the best HF antenna arrangements for the 
Michigan house.

Here's what I'm thinking, in general, but I need some help with specifics.

When I moved to Colorado last July, I donated my tower, triband, beam, etc., 
to an EOC one county to my north, so I will be without a tower.  In 
considering various options, I feel that my best arrangement for HF would be 
wire antennas of some sort.  Keep in mind that I need antennas that will 
accommodate 600 or 700 watts, due to my recently-purchased Ameritron AL811H 
amplifier.

I do not necessarily have a problem with room on the Michigan property, 
although coming up with adequate antenna supports might be a slight issue, 
though ultimately solvable.

What I'm thinking is this:  I'd like to have two dipoles, arranged 
perpendicular to each other, so as to cover as many directions as possible. 
My TS480, and my Tentec 238A manual tuner both have antenna switching 
capability, so switching between antennas will not be a problem.

One of the dipoles that I'll use, of course, will be my trusty Alpha Delta 
DXCC, which I had up here in Colorado, and used regularly for the 
Cross-country blind ops net.

I am trying to decide what to do for the other wire antenna.  I thought I 
had a line on a Carolina Windom, but that seems like it will not work now, 
since the ham who was going to work a deal with me has gone to Florida for 
an indefinite period of time.  I could get another Alpha Delta DXCC, but 
would like to try something that might get me on 160 meters if possible.

Some folks on this list have discussed the Cobra lite series of antennas, 
and I might consider that as a possibility.  Do those antennas cover 160, 
and can they handle 600 or 700 watts?

Also, I have a question about coax.

In Colorado, I fed my Alpha Delta DXCC with RG8X coax, and didn't seem to 
have any adverse effects when running more power with the Ameritron amp. 
Some have told me that this is not a wise thing to do, and that I should 
consider bigger coax, like RG213.

Does anyone have any thoughts on this question as well?

I know this is a lot for one e-mail, so I appreciate everyone's patience in 
wading through it.

I'd like to place an order soon for what I need, so the stuff will be 
available in Michigan, once we are back there for good next week at this 
time.
