Not "may", but WILL. I've pulled out fender mounted mobile antennas using
the standard 3/4" mount and angle bracket. The volunteer fire guy specials.
The unsealed cable shield acts like a soda straw. Even have seen water
dripping out of the radio end of the cable when the plug is disconnected...
scary.

Bob:
If you do remove the balun and need to connect the coax directly to
the feed point, let me suggest this as a way of providing two good wire
leads off the end of the coax:
http://lists.contesting.com/archives//html/Towertalk/2007-02/msg00034.html .
If you use the coax braid as one connection exposed to the weather, it may
wick moisture into the rest of the shield, corroding the connection. My
coax balun at the feed point to my Bencher Skyhawk has this connection at
the feed pont and I see nothing that causes me to want to re-do the
connection.
FWIW.

Bob, likely someone has done that but why would you want to?
If you do make the substitution, be aware that part of the tuning on the
TH11DX include the leads between the balun terminals and the antenna
terminals. You would want to replicate that part of the antenna. Same gauge
insulation covered wires, same spacing and same length.
It probably would suffice to strip the end of the coax back enough to equal
the length of the original wires and apply some liquid vinyl tape to keep
water out of the coax.
Nothing is simple is it?

Has anyone ever eliminated the Balun on the HY-Gain TH-11DX and just used
an RF Choke made of windings of coax?
