Some Antenna Ideas
While I have heard about the slinky idea for HF, why not take a look at some of these other ideas.
Since most people are allowed to put up a satellite dish, why not make this work to your advantage?
For VHF and UHF (and possibly 6 meters) operation you can buy one of those outdoor TV antennas that resemble a horizontal dipole that mount directly over the curve of the satellite dish. I suppose that it could be trimmed to resonate frequency too. Would probably be very easy to trim one for 6 meters.
While you don't have to actually buy the "clip on TV antenna for a satellite dish" You can make your own that closely resembles it for your particular band.
Here's a picture of the sattelite antenna idea for VHF/UHF and possibly 6 meters:http://www.doubleberger.com/TV%2DVCR%2DAccessories/IDC15088/TERK%2DTV42.htm
IDEA #2 (VHF/UHF)
PVC vents on roofs are also an excellent way to make a multiband 1/4 wave antennas. "White" lamp cord that resembles the color of the PVC works best.
How about putting up a fake "vent"?
Hardware stores usually sell these vents pretty cheap. Cut to approx. 19.5" and your vent will make an excellent radiator on 2 meters.
The vent should be located as high a possible, for adequate ventilation of course.
I was thinking about a 6 meter beam in the attic, but it might be easier to construct a 6m horizontal beam out of wire that closely resembles the color of the roof shingles.
IDEA # 3 (HF Stealth Mode)
You can string up a nice long wire dipole by tucking it under that plastic PVC siding used on most of these newer homes.
My favorite antenna stealth trick is to purposely install what may appear to be cable TV wire along the side of your house or building. Make it appear professionally installed by the cable guy himself!
Be sure it looks like it runs from one destination to another. Construct the wire using official "cable guy" tie downs and the whole nine yards.
Be sure it bends around window frames, doorways, and try to make it as long as possible for HF. Heck, you could even put one of those yellow colored "utility tags" on your new long wire to show everyone one in your neighborhood that your newly installed HF antenna was even certified, dated, and initialed by the cable company.
If you think the newly added wire might raise suspicions, you could simply say something like, "Yeah, got tired of that slow dial up internet access. They had a great deal on cable internet access. they installed that extra cable for my new broadband cable modem. I will never go back to dial up again!"
