Has anyone used these? Do they work? Need to go 1000' outside for an event, but 1mW???
I can't usually get that far with 50mW.
If anyone has a reliable way to do this with RF, without breaking the bank, please let me know.
Looking at those FM broadcast band TX as an option. Need this for an annual event, but have others that could benefit from a wireless link. I have several Sennheiser wireless that could be used for receivers, but the IEM TX, doesn't have enough power alone,to do it. Would need expensive helical antennas on each end. Suggestions? Renting something not out of the question,

What exactly are you trying to accomplish? If it is 1 channel of transmission to 1 or many receivers you can rent a Lectrosonics IFB transmitter with as many receivers as you need (http://www.lectrosonics.com/US/wireless-IFB-systems-interrupted-fold-back-ENG-systems.html). The receivers are 1/8" out so you need an adapter. They are very reliable, and sound pretty good.

Yes, 1 source to several locations. Thanks! Will check that out now.

You can also use that IFB transmitter with R400A receivers, which have XLR output and can be powered from AC mains.

1mw over 1000' LINE OF SIGHT is a very optimistic spec. Place a big crowd below the line of sight and a lot is absorbed even if it doesnt block it. Special antennas would need to be used like parabolics or at least long throw Helicals. The Lectro is better since it has more power.

I have a couple pairs of the Applied Wireless packages and yes 1000' even outdoors is very optimistic. 200-300 pretty stable but pass that better be line of site.

Decided to go with the Lectrosonics IFBT4, and use my Sennheiser receivers. This way I can use remote antennas on each end. I'll put active paddles on the receivers. According to my buddy at Lectrosonics, I should be good to go. I should have time before the gig for testing.

Interesting. So these both use the same companding scheme? That'd be super useful info for me to know as i encounter both on a regular basis...

According to Lectrosonics, MODE 3 on the IFBT4 is Sennheiser compatibility mode. Guess they don't want to say Sennheiser. I will let you know once I get it next week and test it out. I too have several other uses for this!

Just note that the Lectro compatibility is with the original Hidyne compander, not the newer HDX in the Evolution and 2000 series.

Any idea how badly it will affect the audio? For this application, it's just wide area announcements using Community R series. Are there other modes that might be better?

FWIW,
I have never been able to get satisfactory results when using Lectro TX with other brands' RX. Although the RF performance was rock solid, I could always hear a little compander weirdness.
However, using the IFB TX with a 400 series RX works beautifully.
On a regulatory note, you must have a BAS-LP license to use the Lectro IFB TX, since it's a 250mW device, and its use as a point-to-point link is not quite authorized by the typical license.

Which i believe makes it incompatible with all the usual Sennheiser IEM receivers we encounter. i.e. the typical G2 and G3 receivers are both Evolution series IIRC.
In other news, what is IFBT4's Mode 6 compatible with? Can't seem to find the answer online.

It's not about using IEM receivers with the Lectro transmitter, it's about using wireless mic receivers with the Lectro.

True. I lost sight of the OP's original question. I would more often be using these with belt pack receivers. In fact, i'm doing that right now... :)

Tested the system out today, works great! Thanks Mac! The real test will be Saturday. Tested the range at a local race track, looks like 1000' easy.
For what we are doing, didn't notice much difference between MODE 3 and MODE 6 with the Sennheiser receivers. Maybe for something more critical it would be an issue, but not for this.
Thanks again!

Mac, Thanks again for pointing me to the Lectrosonics IFB unit. Used it all day yesterday, no hiccups, got complements on the sound and the coverage. Exceeded my expectations. A big thank you! I already have other uses planned.
