Default DTV Antennas Question.

I'm new to this. Could someone tell me the difference between an Active and Passive antenna? Thanks.

An active antenna has an amplifier. In TV reception, the amplifier is usually an integral part of the antenna assembly.

A passive antenna is not amplified.

Makes sense! Thanks for your reply.
I switched to a 1GHZ splitter for my attic antenna after the transition, would a 2MHZ splitter give me more signal strength ?

No, TV uses the frequency bands in the range of 50 to 700 MHz. A 1GHz splitter means it passes signals up to 1GHz or 1000 MHz. Hence it will pass all Over the Air TV signals.

Now DirecTV and Dish Network HD services use frequecies as high as 2GHZ and a little higher, so those 2GHz splitters are used for HD satellite TV installations. Some cable systems might go that high, I don't know.

But the point is higher Mhz is not an attribute but a statement of frequency.

Everyone got confused from more MHz in personal computer being better which is it, but in a computer MHz refers to the speed of a computer.

Just like I have heard cordless phones with more Ghz are better. All that means they are on a different but higher frequency that may or may not give better service.

Even moreover inside a splitter there is nothing active. It's a passive device. The rating merely tells the customer how high of a frequency it will pass, not that it is stronger or faster.

Default More on 2 Ghz splitter

Thanks Piggie for your quick reply.
I take it from your explanation that my 1 Ghz, 2 way splitter will be OK although it is a little bit of overkill. Or should I revert back to a 50-700 Mhz splitter ?
What do you advise for the best reception.
Thanks again.

Either one will work. I would use the 1 GHz one because if you have a channel in the high 40's or up that is pushing the limits of the more narrow one.

Practically, you probably won't see a difference.
