Where to find FM Transmitter?

[BrianMiller]

I looked up a few reviews for the CZH-5A. Some said 2 miles and some said 3000 meters. While it might be a crappy 5W, it's still too much for what I need.

I looked up attenuators--they cost more than the transmitter. I have a handful of 75ohm 20db attenuators on-hand but I don't know if they'll work correctly and safely with the 50ohm transmitter. Not to mention the input wattage exceeds that of the attenuators.

Hi:
If anyone is interested in the iPod transmitters, go to Ebay and search for:

USB 215 TRANSMITTER.

This is the one I used this past season. I left it on all the time, with a wall wart, because if it was powered down, it would not return to the frequency it had been set on.

Also, do a search here for "Spare FM transmitter" for more information.

Ok,.. the seller has a .5w on hand. Is .5watt enough?

Hi:
.5 w is more than enough. Again, work on the antenna, not the power.

Just guessing, but I would say that the 215 transmitter i mentioned is probably no more about 10 mw, at the most.

Here is the device I grabbed.

So you think .5 watt will exceed the 200ft radius? Crap.... more screwing with the antenna...

Hi:
Wow. That looks like a nice TX, but you really didn't have to spend that much money to get a good one. Sorry to rain on your parade.

BUT, just connect it to a vertical dipole type antenna and maybe keep it inside the house. You should get plenty of coverage and not set off any alarms. Just experiment with the location of the antenna and remember, just because you have the capability to go 10 blocks doesn't mean you have to. While big coverage is good for the ego, it is not necessary. All you need is to cover the area near your display with a good, clean signal.

Seems I always have to look twice. The antenna supplied with the TX may be just the ticket. Just experiment with its placement to arrive at the coverage you need.

Excellent,

Unfortunately, the seller was only willing to give me a lower power device that was comparable in price. his $80 5Watt may have been crap,.. his $80 .5Watt seems to be nicer...
