How difficult is the install?

I want to hook an off the air HD antenna up to an HD 720p projector. What is the best way to do this? I want to keep the cost as low as possible without sacrificing 720p HD quality. The antenna has an RF connector. The projector has HDMI inputs, as well as component and vga inputs. I know I could buy a DVR and connect the antenna to it, and then connect the DVR to the projector. But, are there any other options? I would like to do it for less than $50 if possible....the goal is to eventually get an HD capable DVR. Thanks!

No, just the opposite actually. Higher dBi means the RF energy is more focused. A standard antenna might be roughly 2.2dBi and the RF energy pattern is shaped like a giant 100-foot donut. If you use a high gain antenna, the energy gets more flattened out, now shaped more like a 200-foot pancake. So a high gain (like a 5dBi) has less signal going up/down but a stronger signal that goes farther out to the sides. This might actually make some setups WORSE, such as an access point in a basement and a laptop up in a 2nd floor bedroom for example.

Higher gain is bidirectional, that is, the transmitted energy is stronger (more focused) and its receive sensitivity is also stronger. Every increase by 3dBi is a doubling of power. Every increase of 10dBi is 10 times the power. That's the rule of 3's and 10's, it's logarithmic. The rule of thumb is that every increase by 6dBi will about double your distance outdoors, and 9dBi will about double your range indoors.

Note, I made the point above (more focused) to stress that a high gain antenna is an example of PASSIVE gain. This is not active gain, nothing is being amplified and the access point puts out the same amount of output power. The passive gain is accomplished by the antenna focusing down the RF energy pattern. So picture it like the same amount of signal, but shaped a different way. A very simple mental picture is to think of a large round balloon that gets squeezed on the top and bottom. Same amount of air (signal) in the balloon, but now it reaches out further to the sides and less going up/down.

Will the transmitter antenna is divided AM and FM antenna

I'm thinking of buying a Projector. What are the advantages/ Disadvantages of a projector over a HDTV set? What should I look out for/be aware of?

(This answer assumes that you are located in North America)

Probably. Digital and analog TV broadcasts use the same TV antennas. If you get good analog reception now, you should be able to use your old antenna.

Digital TV signals can be fussy about signal quality, so some people will need better antennas.

Despite marketing hype to the contrary, there are no special "digital antennas" or "HDTV antennas".

Have you made one that actually works well?
Please share any plans that work.

Hey everyone, I need to find an antenna, 3 way splitter for my car so the antenna plugs into three stereos. I have the original AM radio, 8track with a radio and a new cd/am/fm/ipod everything stereo.

I was just wondering where they were sold and who has them cheapest.

Thanks a lot!

Does anyone know of a good indoor over the air HD antenna that will not loose the signal or freeze the picture especially when you get close to the antenna or walk around it? I have tried different brands and its all the same if you get near the signal is shot and the pic freezes and audio also comes and goes until the pic is restored again.

Recent want to design a 406M-409MHZ car antenna, how to determine the length of the antenna, hope there is experience in this area or two senior guidance would be grateful,
