BNC Tribander for New TH-F6A
 

I just got a TH-F6A and have been reading about the weakness of the
SMA connector. I'm convinced I need to get an SMA-BNC adapter but I
have found no BNC HT triband antennas. Are there any out there?

The Smiley 270A is a dual band 2M/440, but they claim it will also
work on 440? Any experience with that?

Also, I have been thinking about Gulyas http://www.wa3hrl.com/smabnc/
SMA-BNC adapter in particular, but then I read this article
http://osdir.com/ml/recreation.radio.../msg00041.html
It says: "To minimize the stress on the HT, I use the slick little
adapter BGA-80 from Steve Gulyas. It uses a special o-ring arrangement
that minimizes leverage against the SMA. Works pretty well. Its the
best on performance, but too big to be attached to the HT when worn on
the belt."

Does anyone have any experience with SMC-BNC adapters? Do any good
ones allow you to attach your HT youir belt?

I'd really appreciate any suggestions you may have!

I got an 3' long thin coax cable 'SMA to PL-259' adapter at Houston
Amateur Radio Supply. Good for mobile work, or via 3/4" dia. UHF lo-loss
coax from CableXperts.com up my 50'tower to Cushcraft 6/2/70cm beam, or
via RG213/X to the ArrowAntenna.com 146/440 J-pole on my roof. The
antennas are also a match on 224, but not much activity on that band.

Welll... I had a number of HTs using BNCs over the years. The ones
that were used a lot in general needed the Chassis connector changed
once a year. I've yet to have to change an SMA.

The connector itself on the TH-F6A isn't particularly strong, but there
is a raised ridge around it on the case that the supplied rubber duck
rests on to take the mechanical loads. If you're putting a different
antenna on, what you probably want to do is what a colleague of mine
did: find a nylon bushing that's just the right height to support the
bending load of the SMA/BNC adapter on that same ridge. Rummaging at the
local hardware store he found one that required only a tiny bit of
sanding to make it work.

Then, he did the usual "two right angle BNC adapters" to further relieve
the stress loads.
