Neat little bi-directional Amp...

Anybody used these before?

Our local telco has apparently used these in a few places to enhance in-building SMR coverage. We may be installing one for them in the near future. I hadn't heard of them before now. They look like a cool product. I'm curious to know approximate pricing of them.

I've seen similar devices used before... they worked well, but none were FCC type-accepted. I'd check the type acceptance closely...

FCC type acceptance doesn't apply in Canada. I believe the CRTC is the responsible agency.

What's your problem, dude?

I stated that the units I've seen used were not FCC type-accepted. The FCC would be the accepting body for the US. I then told Todd to check the type acceptance closely... note I didn't say FCC?

Also, last I heard, IC does Canada's type acceptance, not CRTC. CRTC regulates broadcast (radio/television) and telecom, as far as I know.

If you don't have anything to contribute to the topic at hand, simply don't post.

I see on their PDF that they are silent on type acceptance. And they are located in Georgia.

Going to the companies website it seems that they were absorbed by Andrew Corp. I'm sure Andrew will do the right thing if it exists or pull it from distribution.

100mW isn't much power, I can't see it covering 75,000 square feet like advertised unless it is an open area like a warehouse.
Add a few walls to the equation and I doubt it will work very well.

Well, it's the telco's ass on the line, not ours, but I'll definitely check the type acceptance if we install it for them.

I'd like to assume their engineering group checked that out beforehand, but past experience tells me otherwise.
