Just prior to getting back on the air, I had a "top-of-the-line" Lennox HVAC system installed in my home.  I hooked up my rig and immediately enjoyed 10-20db over S9 QRN which came and went as if someone threw a switch.  It didn't take long to associated that with the cycling of the HVAC.  Rather than start at ground zero with Lennox, has anyone out there experienced the same with Lennox units specifically and if so, has anyone been successful in getting resolution i.e filter kits etc.? I'm sure I am not the first Lennox (ham) customer with this problem.

Thanks to all for your comments and opinions.  I am well aware of the shortcomings and disadvantages of compromise antennas such as the TW 2010 and the MFJ 1788. Given all the accolades documented on this and other forums, I was curious as to how each compared in real work on-the-air tests.  These two were only one of several considerations of a way to get back on the air (and also have a portable antenna) given the restrictions in my development.  My first and foremost hope has always been an outside wire antenna as they are generally more efficient and a heck of a lot cheaper.  Ultimately I will probably either load up my rain gutter that's 40' horizontal by 20' tall with a coupler like the SGC and lay out some radials in my back yard or tuck about 100' of wire in a two turn loop vertically inside the siding of my chimney or maybe both.  We'll see how it goes.  Thanks again to everyone for all of the interesting technical information.

Has anyone done an on the air comparison of the TW 2010 (Traveler) and the MFJ Hi Q Loop?  Any comments on indoor usage would also be helpful.
