This provides some spring action, so if the aluminum expands or contracts the materials stay in contact. ** Fix: (If your still reading …) I removed all the nuts, installed split-ring lock-washers. But what about the guy doing work after yours that does not know this stuff !) (Yes, you can buy special receptacles and switches that are aluminum compliant and more expensive. In contact with each other as a mechanical connection, the aluminum has a high coefficient of change of size with temperature and over time will work its self loose (Known as ‘Creeping’). In the presence of aquas solution (a.k.a. If the metals are used outside in the elements, the metals must be separated by material to keep them apart (a.k.a. Steel and Aluminum don’t work well together unless consideration is taken into account for the 2 dissimilar metals. ** Problem: The antenna is constructed from steel and aluminum parts ! Tightened them all up and the signal came back like it was of the first day after the install. Going up in the attic to investigate what I noticed is that all the connections were loose. Worked great at first, then after a few months reception started to fade and become intermittent. ** In an almost all UHF market, this should be your selection. (which I don’t think are even available anymore from this manufacture). Your best reception should come from the 4 bay ‘bow-tie’ shown on the right. But before buying, check the Station Finder to see what stations are available in your area. Check on my antenna section for more info on what types are available. You might be able to get some channels if you get a real indoor antenna (which costs $40 or so) or an outdoor roof/attic antenna. If your TV didn’t find any channels, all is not necessarily lost. It’s just a way to see if everything is working. Remember, this is just a quick and dirty “antenna” – it’s primitive and not ideal in any sense. Even if you only got a few channels this way, it’s a good sign. Since this test uses a very crude antenna, you can will get significantly more channels if you go out an buy a real antenna like the Mohu Leaf. However, if you want to start with an indoor antenna, I recommend the Mohu Leaf (which is what I personally use). The setup above is just an experiment.Īn outdoor antenna will get you the most channels. If your TV found any channels during the test, congratulations!! You are a Cable Disabler!! You can receive broadcast digital TV for FREE! A digital signal would produce the same effects as a weak signal: either a clear ghost-free picture, or loss of audio and video, depending on the severity of the multipath. Again, this may be annoying but is still viewable. An analog signal would appear with a "ghost" image, which is a slightly displaced and faint duplicate of everything in the picture. However, if the digital signal was too weak, it could cause the audio and video to cut in and out or disappear altogether.Īnother example is multipath, wherein some of the TV signal bounces off a tall building or other structure and arrives slightly later than the direct path signal. In contrast to this, a slightly weak digital signal would still be sharp and clear. For example, a weak analog signal would appear on the TV screen as a "snowy," or grainy, picture, which may be annoying, but is still viewable. Digital TV is far superior in quality and clarity than analog TV, but a weak signal can sometimes cause problems with reception.
