Yes, it on the way to Brazil. I heard it few days ago...
I know this is off topic but has anyone on this board ever had BPL
interference on satellites or HF bands? If so, how did you get rid of it?
I'm terribly sorry our representatives haven't done enough for us but they
will realize by the time BPL starts interfering to military and other
essential communication needs.
I'm looking forward to hearing from you.

>> ... Would the Arrow antenna work well for a fix rotor antenna?
Is is not the most rugged of Yagis for external mounting. Its beauty
is its ability to be broken down quickly for transporting. And
remember: if you have the model with the duplexer bult into the
handle, max power is 10W. Otherwise, max power is 150W.
The Laird/Cushcraft AR-270B is a much more durable dual-band Yagi for
external mounting.
>> ... Those that use the Arrow antenna, how do you like it ...
It is the ultimate commercially-made FM sat antenna for low-power
operations.
>> ... how well does it really work?
Magnificently.
>> ... What HT's are used for it ...
Any 2M or 440 HT can use it. And if you get the model with the
duplexer built into the handle, you can use dual-band HTs and your
Arrow to easily work the FM birds.
I use the Yaesu FT-60R HTs during my presentations and demos.

Guys,
I also tried this basic setup with a single Arrow.
My "regular " antenna is 14 elements on 2 meters, 20 elements
on 435.
The Arrow worked pretty good, actually! Not as well as the
big beams but plenty good for LEO work. Just remember they
are only good for about 100 watts or so, I think.
