My hoa is  a litte weak and I think  I can get away with a directional antenna if it is not real big. I would like a hex beam but that may be too large. What directional antenna would give me good results without standing out. I currently am using a 6 btv with a Kenwod 590 s.

I'm in the same boat as you nad is getting ready to put up a 6BTV painted grren to match the trees.  I'm going to mounted it to a DXengineering tilt base and tilt it up when I use it.  THat's going to get old fast.  Try looking at TGM antennas, they're a Canadian company.  I haven't purchased one yet but check out the reviews here on eham.

BTW how's the 6BTV working for you?

The 6btv does a great job fpr distance. Can't get anything local. I too use the dx engineering tilt mount and it is a great product that makes raising and lowering the antenna a breeze. I put down 40 ground radials and that helps my signal dramatically.

     What bands of interest? My 20m hex is well camouflaged at 25 ft.,but I wanted a dedicated 30m antenna with a little directional ability so ended up with 2 30m inverted Vs at 90 degrees switchable by a cheap 12v dc relay,my lot surrounded by trees on three sides so the 30m Vs are also hardly noticeable.

A half-square might do the job, especially if you have trees available.  It tends
to be a single-band antenna, however.

W1JKA: do you see much difference when switching between 30 meter antennas?

Yea, what band(s) of interest?  The Extended Double Zepp provides gain/directivity (see 8-40 of ARRL Antenna Handbook), but they're for single band, but can be made very stealthy.  There is a mini-Hex Beam from K5BOB that also may be of benefit in your search.

Re: KU7I
            
        Actual operation results: Although I was expecting more distinct directional advantages, I found the main difference between the two was that by switching, usually one was more quieter than the other.Being a qrp/cw operator this means I can most always make contacts even in unexpected directions  that I would not otherwise hear with a fixed single wire antenna. Short of a rotateable 30m hex,this is my best 30m experiment to date and am very happy with it.These results are from my QTH conditions,propagation paths and 28 ft. height,other QTHs will no doubt vary.If I had the space I would have also tried WB6BYU suggestion or inverted U(yew) only rotateable on mast or hanging from tree limb.  Anchors Aweigh!
