I'm thinking of installing a wireless home security system running on 868
MHz (FM). I run up to 100 watts through the built-in ATU, into an Elecraft
balun, open wire feeder and 88ft dipole at 30ft. Has anyone any experience
they can share please? Am I likely to trigger the alarm?
Thanks
Dav
Both I and K0CF have wireless home security systems that I think run on 900 MHz
or so. We both run in excess of 500 watts to K4KIO hexagonal beams at 35 to 40
feet. Our towers are bracket to the house. Neither of us have experienced any
problems.

Alarm systems in general, at least in North America, are notoriously bad
for RF susceptibility. The coupling mechanisms are primarily poorly
filtered signal wiring, Pin One Problems, poor circuit layout, and poor

Don't know what his system will be like, but the system I have as absolutely no
wiring between any of the components. Everything is wireless. Experience of
two of us has been no problems while running high power levels using good
equipment into well designed antennas.

David,
I suspect that you'll probably be OK going wireless, especially running only
100 watts. Our security system is about 22 years old and is a WIRED system,
meaning a lot of wires (antennas!) running through the walls of our two story
home. With my K3 running barefoot at 100 watts, I experie

I have Protection 1 and noticed an increase in noise level once the system was
installed especially on 6m. I moved my antenna from above the house to my tower
that is away from the house and the noise reduced significantly. Other bands
did not seem as affected. The antenna was above my house and
I've used a wireless home alarm system for 13 years with hf/vhf/uhf
antennas in the attic of a 3 story townhouse. The documentation doesn't
include specs. The antenna on the master unit is approximately 13 cm.
Depending on whether that's a quarter wave or full wave, it's in the
bottom or top
My alarm system uses a combination of wires, for the doors, and wireless for
all windows and motion detectors. I usually run the K3 with the KPA500 at
around 450-500 watts and have no problems whatsoever!
