I've got a Yamaha T-70 tuner plugged into my basement system. The only antenna I use now is a T-square taped to the wall. The local, 50,000 watt station I listen to comes in okay, though maybe not as good as it could with an outside antenna. Signal strength on the T-70 is measured by 3 green lights. Only 1 light comes on, and I'm wondering if I could get 3 lights if I attach a wire from the tuner's 75 ohm port to the outside antenna on our roof.
There might be drilling involved and other inconveniences, which make me wonder if its worth doing just to get another green light or two to light up. Thoughts? Thanks.

It's a cheap experiment. Most good antennas can be had for less than 100 bucks
As others have stated, you can indeed get better reception with an outdoor antenna. A yagi design will give you gain for a stronger signal, and a stronger signal will give a better SN ratio. However, an outdoor antenna can be a major undertaking and expense. If you prefer to stay simple, you can improve your simple dipole. Check this site out for good info on dipoles, and scroll down to the section called Collinear Antenna for a dipole design with 3.2db gain over the simple 'T' dipole. Like the simple dipole, it is directional, and getting it higher will help.
Thanks for the info, I might look into that.

And with a rotor even better.

A directional yagi can improve reception by orders of magnitude.
The simplest first step is to get an FM antenna and hang it in the attic. Some people use the old Finco FM5 design - diagrams are on the web. Reception won't be as good as up on the roof, but it should still be a huge improvement over your folded dipole. Add a rotor so you don't have to go up there to change direction.
Installing one on the roof is actually pretty simple as long as you know how to affix it to the roof without causing leaks. Pay close attention to grounding requirements. If in doubt, have a licensed professional do it. Antenna retailers and web sellers often have lists of reputable installers.

You are out, maybe $35-$45 dollars, but, at least, you will know.
If your station appears worth listening to, and since one light really isn't much for signal strength, you may get a big improvement.
Then, it is height and position that will matter the most.
If all your signals are in the same general direction, and you can use a directional antenna, that is best.
I am not a fan of the loaded whip antenna as it always gave me too much multiplath and also cost about $100.
A temporary experiment, something to amuse me when my arm was in a sling, about fifteen years ago.

until the cable reaches its limit.
I bet, it'll be a an excellent clothes line as well. And he doesn't have to worry about the rain either.

If you have a long enough extention cord you can take your tuner and T antenna on your roof and see what that does. a directional antenna will increase your signal strength even more.
If you have an old TV antenna you can drag onto your roof that will give abetter indication of signal strength than a T antenna.

Never assume anything I post is accurate.
Thanks for the advice. I might try that.
The higher up any antenna is the better. Is the antenna on the roof able to cover US TV CH 6 (approx. Band II) and is it pointed at any particular FM transmitter or not?
The best results will only come when the tuner is driven into full quieting off a multi-path free signal.
A ribbon dipole in a basement is likely picking up the reflections in the basement.
