- No, but according to sources, improvement will be minimal if interference is the issue.
Proper set-up/frequency selection is the key.. especially with a low budget system.

distance is the issue.

Re: ew 100 g2 transmitter at 100 mw

use the rack mount diversity receiver with external directional antennas. i've made this work at 1500 ft using the stock 30mW transmitter. having a clear frequency is paramount.

Re: ew 100 g2 transmitter at 100 mw

30mW to 100mW is pointless. It will have very, very little impact on range, and for somebody to do it properly needs access to decent test equipment to ensure you don't remove the factory set filtering that allows adjacent channels to function properly. Poorly done gives a rise in output on a meter but can be simply a rise in spurious emissions which you do not want.

Aerials with gain are the successful solution as mentioned above.

it sounds to me that there is no differences between 100mw transmitters and 30mw transmitters.

Apart from a VERY short battery life....

Many years ago Sony had a 'linear amp' for their 900mhz radio mics, I asked a sales rep at a trade show what was the battery life when running the amp? His comment 10 minutes, JUST enough for a news cross.

To get a noticeable improvement by upping power, 10dB is the often quoted figure - 1W to 10W, or 10W to 100W. 6dB is a very small amount of extra power.

Upping the power also ups the spurious emissions.

You will get better range by careful positioning of the transmitter and receiver.

If you are using a mains receiver, use the Sennheiser "shark fin" antennas as these have a 3dB boost in reception power.
