[TowerTalk] N6BT, Force12inc and JK Antennas

[chetmoore]

Not much to add to what Tim said. If you are going to an 18 foot boom, as
opposed to 10 ft or 12 foot,   why not get as many bands or elements on that
boom while you are at it  Without affecting the performance on individual
bands.  The spyder beams, hex beams are super light and can go in smaller
carrying cases and can use lighter rotators. Spyderbeam/hex may have issues
when permanently installed in areas where you have snow and ice but they
seem to have done well with the more recent dxpeditions. If I was doing a
dxpedition, spyder/hex Would seem to be the way to go.

Hello John:

I work at DX Engineering, so maybe I can help clarify a bit.

You know I love antennas and I really loved the TX-38. It was a super
performer (10 meters was really good), I used it on Field Day for two years
with a triplexer - it was awesome! However, for the reasons several guys
have pointed out here it did not sell well (even with deep discount
incentives). Many guys choose the Bencher Skyhawk - a larger alternative to
the TX-38 with more performance "bang". 8P5A and many others love the
Skyhawk!

The latest "hot" high quality 5 bander (20,17,15,12 and 10) with a 6 meter
add on (makes it 6 bands on one short boom) is the JK NAVASSA5. You can see
it here.

Bummer, I was not aware that DX Engineering discontinued the TX38. I know
that a lot of work went into optimizing this yagi for all three bands and it
also had four 10m elements. I think it would have been a perfect contest
expedition antenna.

however the original poster was looking for a five band beam. The C3 and the
TX38 are not. John KK9A To: <towertalk at contesting.com> Subject: Re:

2014 09:18:07 -0500 The C3 is the best short boom tribander out there in my
opinion. I have used them around the world. They are a clean pattern, smooth
SWR across the full band performer. At the end of the day, the gain
available is a function of boom length primarily. On 15 and 20, you are
going to help yourself by stuffing another element on a short boom. On 10M,
the argument could be made that another element would add value to this
antenna, but the antenna works as a nice package. On 12 and 17 - its just a
rotary dipole essentially - so if that's someone's interest, this isn't the
antenna for you. Nice advantage for DXpeditions, you can break this baby
down into a golf case. And there are no finicky little motors and control
lines to worry about. 73 Ed N1UR
