Hi all,
This probably isn't the right place to post this, but I figure it may
be the best place to find the experienced minds that may be able to
help me with this litlle problem I have.

I need to source some antennas (to supply to someone I work with), and
they must have the following specs:

870-900MHz
5 dB
RG58/U cable (at least 5 feet long)
RA-TNC (Male)
Magnetic mount

As for the cable and connectors, I can buy them separately I guess and
assemble as required.
I have been getting PCTEL Maxrad ones that do the trick, but I'm
having major supply issues (like 2 months wait time).

If anyone has an idea where I can find these things, or what else may
work, I'd be very grateful for some pointers.
Thanks in advance
