The original poster used "fire department" and "EOC" comms in his original
post. That, to me, demands a "step up" in integrity of the radio system. Those
phrases, to me, mean that the safety of the public may be involved. And that,
to me, means no "homebrewed" ham antennas should be on the front
I don't think we're talking public service frequencies.
I think we're talking ARES/RACES/WARN backup on amateur bands.

Do you also demand commercial quality radios?
Here, it's standard amateur transceivers, antennas and power supplies.

depending upon homebrew comms equipment for critical emergency communications.
This is not demeaning to the amateur radio community at all. Amateur radio

Only because they have nobody on their staff who knows what an antenna is.
They don't pay high bucks for the fun of it.
I mean, does your local police department and city works comms centers have
home-made Yagis on their installations? Of
course not.

The Amateur Satellite Service isn't alone in suffering interference on its
frequencies, see this BBC report on Radio Frequency Interference to the ESA
Soil Moisture and Ocean Salinity (SMOS) spacecraft.

I've adjusted the values some to try to prevent or at least slow the
power cycling we've seen outside of eclipse transitions. The reports via
email have been very helpful, even if you don't get an immediate reply.
Please keep sending them if possible for now. Thank you to PY5LF, ZL2BX,

I am looking for a easily reproducible yagi for 70cm 4 elements. I have been
assigned to make a better link between two firestations where we have two EOC
stations. Suggestions or links appreciated.
