Wireless video transmitters?????

[jmbrooks]

I would like to transmitt audio/video from my family room to my bedroom wirelessly. I found a few options and want to know if anyone has any experience with them:

RF 2.4GHz or 5.8Ghz

or

UFH

I found a Nippon UHF video transmitter on eBay for about $30 but am concerned that the picture quality might be poor. This would be a great option as I would not need a reciever at the remote TV.

My computer network is hard wired so that will not be an issue with the RF type. I do however have 900Mhz and 2.4Ghz cordless phones.

Any advice would be great.

I recently got a little X-10 unit that transmits from my office to my kitchen (through a wall) about 15 to 20 feet away. It works okay. Can get a little interference when the microwave is on. Not sure how it would work across a floor.

I've been using wireless a/v distribution for over 10 years. I currently use one master X-10 tx with four X-10 rx (all @ 2.4 mHz) to distribute composite video/mono audio to 1) a bedroom/bath; 2) another bath; 3) my office, and 4) the kitchen. I live (mostly) alone in a 2 BR apt, so I can do this w/little or no problems or conflicts with indigenous personnel.

My issues w/wireless are relatively minor, but for your edification:


effective range through walls/wiring maxs out at about 35'-45'


microwave ovens also operate in the 2.4 mHz band; my MW knocks it out altogether, and my next door neighbor's MW just degrades picture and sound enought to be irritating to me.


cordless phone using the 2.4 band will cause interference or make for interesting listening, depending on how you look at it..


others within range can tune in to what you are viewing, so be careful what you put out over the air, if you know what I mean. :sure:
Despite these probs, I find the advantages of wireless far outweigh the disadvantages. Years ago, I tried a single 900 mHz rx/tx set I got on clearance but could not get it to work. I haven't tried 5.8 mHz, but I were to decide to upgrade, I think I would go through my cable wiring with agile UHF modulators instead.

I'm just thankful my neighbor doesn't try to microwave the Thanksgiving turkey very often. ;)

I'd really like to know if anyone has tried the UHF transmitter.

As per FCC rules allows you use part 15 video transmitter on 902 to 928 MHz "AM video" 2.4 GHz "FM or AM video modes" and 5.8 GHz "FM video"

As for the power output 900MHz "0.01 Watts" 2.4 GHz "0.100 Watts" as for 5.8GHz I am not sure what the power is at that "0.01 Watts"

No antenna gain or no external antenna as per FCC rule.

Not legal to transment on TV broadcast bands channel 2 to 69 unless you have FCC licenses same goes for Ham radio bands too.

I know part 15 rules is too strict, and I think it shoud be at least 1.00 watts of power in order get the signal across the house.

Stay away from am video modes and stick to FM video since it's does better job of getting the video across the room.:)

Have fun with your very own TV station!:D
