hi techies,
i want to reduce the range of a radio transmitter do i just simply reduce the length of the antenna? can i replace the antenna with just a piece of common wire? thanks for any help.

wat transmission (device) u wan to reduce?
a video and audio transmission set.
my set max range is 100ft. i wanted to reduce it by half.
If you have a removable antenna, you can insert a 6dB attenuator between the transmitter and the antenna. This assumes you're talking about free space propagation. For indoors, builtup, or otherwise obstructed environments it is extremely difficult to predict the range.
just cover the antenna with different thickness of materials, then choose the one you want? :think:
sounds like a good solution. 6dB attenuator cuts the range by half right? can get it in simlim tower? any idea what's the typical cost?
6db cuts the transmission power by half... but it does not mean range is reduced proportionally.
note the attenuating frequency.
Littlewolf is rite in highlighting the diff between spec range and real world performance.

Why would you want to do that?
Beyond privacy reasons, it is only courteous (and good, in some cases mandatory practice) to use minimum necessary power (and thereby reduce interference/RF pollution). Same reason why one should adjust the volume of one's radio/TV set to a level where the neighbours are not forced to listen to it ...
