If you're buying anything from M2 expect poor customer service and a
bad build. I have more to do tonight than list the screwups those
people have done. They actually charged my credit card and THEN 2.5
months later (after finishing another manufacturing cycle) shipped the
product (upgrade kit for a KLM kt-34a)!!! Not to mention having to use
a dremel on the "CNC" hardware. The UHF antennas use a cheap white
plastic insulator that cracks, allowing water ingress. Remember the
$200 circularity switch that you need to buy? Junk after 7 years.

Considering what these people charge, I'd expect teflon.
Because I'm a glutton for punishment, I purchased another antenna from
this bunch of rejects (These bozos actually had the balls to cancel
two credit card orders for parts!). It was cheaper than ordering one
from Europe. I guess at $800, lasting 7 years, it's just over $100 a
year to use this, then throw it away.
The antenna has 21 pair of elements. 14 pair (!!!!!!) were miscut. 13
by 1/16 and one by an 1/8. (I took pictures because I care!!!) That's
a real problem where the elements of the antenna are 1/16 th of an
inch different (most). Took me almost two hours to verify what they'd
done and decide that regardless of what screwups they'd made, it was
Seems to work. I've no way to test it other than swr and on air usage.
Take care to read the Gulf Alpha page. Last I looked, the satellite
antennas were out of production and he was reserving parts/service for
original owners, only.
