My arrow antenna is over 10 years old and several are bent as well. I
wonder if it's worth it to get new ones? Does a little bend affect the
performance that much?

It's a bit of threaded rod in the end of an actual arrow (at least
that's how the original article did it). You'd have a hard time
rethreading the threaded rod and, I'm not sure you could easily remove
the rod either to re-insert.

A little bend isn't going to be a big deal.

Ahh yes, my mistake... Anyway there is a spare parts list that came with the
antenna (I have it) but it does not list size, it says 2 - 1/4 stud.. but
that does not answer your question..
If you need this list or would like it I can scan it and post it or send it

So you guys got me thinking, after looking at these elements and measuring
it realized something... these look like Aluminum Arrow shafts, and the
inserts might be the arrow broadhead insert.. which all parts are readily
available at most sporting good stores for building you own arrows (yes I am
a hunter and used to bow hunt)
I will double check this and let you all know, I'll have to do this later
today after I'm off work.. but if this is the case replacements should be
very easily created.

Message-ID: <14efece44bd-15b4-37133@xxxxxxxxxx.xxxx.xxx.xxx>

Interesting.
Only a few days ago there was a comment that a satellite launched 15 years
ago was transmitting on 144.390 which was being used for weak signal meteor
scatter in Europe. That was unintentional and in any case only sent a couple
of very short beacons per minute.
Now we see another satellite 'licensed' very recently using exactly the same
frequency and a lot of other satellites transmitting on frequencies
allocated to repeaters and other services.
I presume the IARU were 'informed' of these frequencies rather than
coordinating them.
I wonder if the head of licensing in Bejing is the same chap who thought the
Anti satellite missile test, that produced thousands of pieces of space
debris, was a good idea.
(rant over)

The commercialised Arrow design was based upon an article on using
arrow shafts in an antenna.
Not a surprise at all. ;)

I'm fairly certain that mine, purchased more than 10 years ago, is using
actual arrow shafts, not something based on arrow shafts.
And I'm 95% certain that it's 8-32 threaded rod that connects them. It
looks like 8-32, and I pulled a random "this looks like an 8-32 nut" out
of my bin of random machine screws and nuts, and it fit just fine.

David,
I noticed the frequency selections for all of those satellites. It is nice
that we may have 6 transponders that don't have overlapping frequencies,
which could make for some interesting times ("Which of the 6 will you be
on?" - for example). Seeing how some of those downlinks are at and below
145.800 MHz could cause many new issues with terrestrial and (for
145.800 MHz) other space operations. Also seeing APRS at 144.390 MHz
(North American APRS frequency) and an FM uplink at 144.350 MHz on
LilacSat-2 (CAS-3H) won't make some any happier.
CAMSAT filed for IARU frequency coordination in 2012:
http://www.amsatuk.me.uk/iaru/formal_detail.php?serialnum=264
but it doesn't appear to have gone anywhere past the filing step. I did not
see frequencies listed on that web page, nor did I see the CAMSAT satellites
anywhere else on that site. I can only guess the Chinese licensing
authorities are making full use of the 144-146 MHz range that is permitted
under the international (ITU) radio regulations for amateur satellite
operation, regardless of the voluntary bandplans observed around the
world.
73!

The CAMSAT filing you referenced is for the CAS-2 series not yet
scheduled for a launch, not the CAS-3 series on this launch.
LilacSat-2 has other frequencies coordinated:
http://www.amsatuk.me.uk/iaru/finished_detail.php?serialnum=395
The CAS-3 series is pending coordination here:

Hit send before I could attach the last link, for the CAS-3
coordination request.
