4.0 out of 5 stars Good product for the price, May 30, 2011
Verified Purchase(What's this?)
This review is from: Skylink HA-434RTL Long Range Motion Alert Kit; Be notified of your surroundings. (Tools & Home Improvement)
Receiver came with wire antenna, I'm getting flaky connection(100+ ft thru walls), replaced with telescoping metal antenna now works flawlessly (see uploaded image).
Con: When transmitter/motion detector losses power/battery, it has to be paired again to the receiver. The idea of adding a switch to the transmitter/motion detector to conserve battery when not in use won't work.

So far it's been working flawlessly for couple of weeks. I'll update transmitter battery life when I get a chance.

Update: The motion sensor battery on mine is still working after 7 months...nice (the sensor probably gets triggered 6-10 times a day, if that makes a difference from the other reviewers)

Bryan N, I suppose you can just take a heavy copper wire and replace the existing antenna. Antenna lenghts of 0.66 m, 0.99 m, 1.32 m should work. Make it stick straight up.
BACKGROUND: 900 [MHz] wavelength = 300000000 [m/s] /900000000 [Hz]= 0.3333 [m] (same length as the factory installed antenna = one wave length). You are simply adding wavelengths in muliples to increase the gain. I suggest to use heavy copper wire to reduce the resistance.

300000000 [m/s] is the speed of light (in case you are wondering).

Thanks for the review.
What type battery does the base station take and how often have you had to change it? Also is the 9v sensor battery still good a this date (28-FEB-12)?

What's involved in the pairing prcess that makes a switch in the transmitter/motions sensor a no go?

Roadtrekker says:
The base station does not use battery. It comes with an AC adapter. The 9v battery in the motion sensor transmitter still works since day 1, I haven't replaced it yet.

To pair the units, they need to be close to each other while pressing the pairing buttons (if I remember it right). To add a switch in the motion sensor means you need to re-pair it to the base unit everytime you switch it off.

Silly question, but how did u cut a clean hole in the shell for the antenna base? I assume a drill but want to make sure before I ruin my new device.

Thank you in advance,
