[misterhouse-users] Passive antenna for motion sensors

[Scott R. <sc...@th...>]

I recall reading some time ago that you could improve the range of 
MS12a's and the like by cutting a piece of metal hanger and placing it 
above the motion sensor. The length of the hanger needed to be cut to a 
certain length that correspons to the period of the wavelength of the RF 
signal. I've spent an hour or so trying to find any information on just 
how long a piece of hanger i should use. I had one of these set up with 
an outlying sensor and it worked great, but the wire got, er, recycled 
for another project. anyone recall the correct length for the wire?
