How to detect signal

I had the local wireless internet provider come out and see if i could get service. The signal strength was something like 69 dBi and they said I needed 82 dBi (if I remember correctly) so I can't get internet. I plan on getting an antenna mast to mount on my roof and I don't know how tall I need. Is there a way I could get some type of equipment to detect the signal so I could experiment and see how tall an antenna mast I need. I don't want to steal internet just see if it is there. I believe the frequency is 2.4 Ghz. I have called the WISP and their answer is I don't know.

Probably best in the wireless users forum.

You probably have it reversed, you had -82db, and they want -69db.

-82 is a good long way from -69db. You can buy equipment to detect signals, but they should have given you a recommendation on what to do, how high to go, a simple mast on the roof might not be enough, and you can only go so high with those (8 feet) in a tripod without guying it off.

Id also be weary of a WISP that answers your questions with "I dont know". Id see if you can get someone back to tell you what you need to do.

Does not make sense. -82 is weaker than -69. Could you have your numbers reversed?

Like the others said. Those numbers are reversed most likely and the span between them could be difficult. When we test we actually will go 20 feet or more above the roof line. That way we know if a tripod is an option or if not then the customer at least has an answer on how high is needed with a tower to get service. Some customers have searched out there own antenna towers (used) and installed them for us. We come back climb them and install.

If you willing to go through the work of installing an antenna tower then tell them so and let them know you just need to know how high it needs to be.

If they are not willing to discuss those options with you my advice would be not to pursue internet through them.

If they had line of sight, a mast probably wont help.
You could just be too far away from the transmitter (miles)

No such thing.
Additional 20dB antenna gain would remedy the problem.

At risk of starting a debate (that is NOT my intention though), I wanted to reply with a more serious answer..

Ham's actually do use 2.4ghz for "moonbouncing" signals, It's also referred to as "EME" for Earth Moon Earth..

Granted it's a whole different ballgame shooting a signal over ground vs the perfect line of sight example I have given.. But with the rather intense and sometimes huge antenna's or antenna arrays, it can be done..

Just modest 2ft size, depending on frequency.

I think it was "additional 20db" on top of whatever 2.4ghz antenna he used for his site survey.

2ft dish adds about 20db to 12cm 8dBi patch at 2.4GHz

I can easily understand any serious company stating what the customer interprets as "I do not know" simply because they really do not know. They are never going to know and they do not want to know. You can keep asking but they really do not know. They are politely saying your not in a serviceable area. I can see the next post.
I put up a 100 foot tower, cause my "whatever" said signal was there and they still won't hook me up.

I know you want service, but I think you have been told they will not provide service there, and may have to accept it.

Um no. A 24 dbi 2.4 GHz grid dish is about 30" x 24" and weighs about 5 pounds...

A 27 dBi solid Parabolic at 5.8 GHz is about 20" in diameter and weighs about a pound...
