Eggbeaters have been discussed hundreds of times on the BB...just do a
little research and you'll find that they're terrible for working sats.

A cheap yagi is probably the best thing to get started with an HT.
http://www.wa5vjb.com/references/Cheap%20Antennas-LEOs.pdf
The most effective omni antennas are probably parasitic lindenblads, but
omnis are always a compromise, especially if you are not in a very low
noise area.

Some other options include CJUs and IOios.

"Back in my day...". Give me a break. Times are changing and the hobby is
evolving. I've never even heard you on the sats, so obviously you're not
chasing grids too hard anyway, so why do you even care?

Complaints from whom? I?m still at work but have kept up with about four
rivers giving out grids today via Twitter. Sometimes you have to adapt and
overcome. That?s what I?m trying to teach my young YL daughters that are
active everyday on satellites. Use all the tools at your disposal and have
fun.

Oh, that's right, you're the dude who's still butt-hurt because I called
people out about bullying new users who ask about tripods.
You're the dude who assumed that since you never heard me TX that meant I
wasn't operating at all.
You're the dude whose reading comprehension is lacking.
And you seem to be the dude who thinks that if you know one aspect of
operating you know them all and can't ever admit ignorance.
Please don't bother to respond to the thread any more -- I know I can't
trust any advice you might give, out of only the best of intentions, because
you make too many faulty assumptions.

I disagree. KG5CCI was kind enough to allow my daughter to make her first
linear satellite contact with Europe using his equipment. That created a
thirst that she wanted more than FM satellites. Sometimes the truth hurts.
I?ve been doing this for a couple of decades and now have a General daughter
and another daughter studying for her Tech and making contacts with me as a
control op. The best thing for kids is to set them up for success where they
can make a contact using appropriate equipment.

Arrow II antenna. In your hand... Any yagi. In your hand... I operate
portable in Southeast Alaska, which as far as weather is like Western
Washington but colder, wetter, and in general more severe. And I use an
Arrow, in my hands, winter, summer, whatever...

Hi,
I've tried to work a good pass of CAS-4B over Europe few minutes ago: calling
cq for most of passes and listening over the bandwidth I got no responses
and I haven't heard anyone...
Just a case or the satellite is almost unused?

Hi Devin,
A nice & clear calculation and construction article from ON6JC/LW3HAZ
on eggbeaters is at:
https://jcoppens.com/ant/qfh/calc.en.php
Hope is useful,
