I have a cheap Accurite wireless thermometer from Walmart. Is there any easy way to boost the range? I tried lengthening the short wire antenna inside the indoor receiver, but this didn't help. Maybe I should have lengthened the sensor antenna as well?
Any thoughts would be appreciated. Right now, I'd say the unit has about a
Thanks, Jack
You could try placing it on a ground plane. Something like a biscuit tin lid should do. Probably won't double range but might get you some of the way there.
Well, it depends on how much of a science project you want to make out of this. You could add a cheap mini-circuit rf amp 'tween the rf output and the sensor antenna. A ERA-33SM gets you about 15dB of gain (dc-3000MHz) and only cost $1.72
Experiment with a corner reflector behind your sensor and aimed at the receiver. See

Use antennas that are actually cut to resonance, or even directional antennas.
Good Luck! Rich
