Poor outdoor antenna performance

I recently installed an outdoor antenna to my MD T108 which for years had been used with an indoor mounted MD ST antenna. I thought I would get much better performance, but alas no. The antenna is Winegard HD-6010 HD mounted on the side of the house. The coax is normal tri-shielded RG6.

The signal strength remained the same, which is fine as it is quite strong without much multi-path. I'm getting noticeable static, however, especially during quiet segments of classical music.

I'm open to ideas/suggestions. I tried rotating the outdoor antenna as much as was easy to do from a the top of a ladder, with out much difference. I upgraded to Channel Master CM-3203 High Performance Outdoor Balun Matching Transformer Deluxe--again without any real difference.

The curious thing is that when I replaced the outdoor antenna with the MD ST the same (roof mounted) location, the performance failed to improve. This is curious because the I would have thought that if the ST inside was as good as the roof mounted antenna outside, moving the ST outside and further up would better both prior opinions. ...but it didn't. Which suggests that something else is going on--a bad cable, maybe?

I could move the antenna higher, with would likely require the help a handyman, I could change the coax, I could even try a different antenna. Do you have suggestions?

Thom,
The HD 6010 antenna is an omni directional unit with roughly the same gain as the MD ST it replaced. You've confirmed this by rotating the antenna and not seeing any signal strength difference and by swapping the Win and the MD in the outside location. You need a yagi antenna which has more gain than the omni units but the downside being its directional and needs to be pointed towards whatever station you're trying to receive to get the most benefit from the design.

Amazon has a Stellar 3 element here:


There is also a 4 element Stellar out there model # 30-2460 available through Newark but its out of stock right now,

Hope this helps.

1) Get a folded dipole, yes, the $2.99 kind, tack it on a T-shaped piece of wood or plastic, and play with it. It should out-perform the omnis you have by quite a bit, though you have to rotate it as it is directional. If you get acceptable performance with that, you're done.

2) There was one indoor omni I had that actually worked, unlike the ripoff MD whips (yeah, been there) but I forget who made it. It was a cardboard tube, about 7-8 inches diameter and about 48 inches long. It was lined with some kind of screen. If you find anything like that, try it. Here's a pic.





3) There is NO substitute for a yagi on the roof with a rotor, and the cost of the hardware and the pro to install it is surprisingly modest. If you have an attic, hanging one there comes close, and you can use a rotor there as well. Channelmaster still makes some, and the old Fincos, if you can find one, were excellent. For rooftop installation, hire a pro, or you risk losing all your gear, at least, and possibly your house or your lives.

Good luck.

Ahh, now the results make a lot more sense.

Thank you.
