That's fairly close Steve, but I think with tapered (stepped) sections the moment of inertia is variable over the length because the cross sectional area...
Last Saturday, during a heavy cell burst with gusty winds, my hexbeam came crashing down. I guess you could say it was raining cats, dogs, and hexbeams. The...
I'm in the process of building my new hexbeam and have a question. I am attempting to tune the reflectors using an antenna analyzer driving the directors and...
SWR isn't really a big deal for me and my likely feedline choice and length. I am interested however if there is any use to tuning to the CW portion (low end)...
Jim, Magnitude of the Reflector current *does* give an indication of broadband hexbeam tuning, but it's not a very easy method to use. Firstly, peak Reflector...
Steve, My wire diameter is 1 mm and the diameter of the PVC jacket is 1.5 mm. Many thanks for your assistance. -Jim To: hex-beam@yahoogroups.com From:...
Jim, That's quite a thin jacket - 0.25mm - but assuming it is correct, the scaling factor you want is 0.982. Multiply all wire dimensions - but not the end...
Jim, The tuning is a compromise between Gain, F/B and VSWR. If you re-tuned to put peak F/B into the CW segment, on 20m/15m/10m you would typically improve the...
Yes, jacket is thin. I looked up the wire and I'm pretty sure it's Belden 9982. Specified jacket thickness is 0.25 mm and the specified diameter is 1.45 mm...
Steve Thanks, that's just what I wanted to know. Here in my Maryland location F/B vs gain would be a good tradeoff to reject strong US stations in pursuit of...
Jim, You'll get pretty close by assuming that the published dimensions place peak F/B about 1/3 the way up the band from the bottom band edge; then apply the...
... Leo, since 6 meter wire lengths are the same in both of your charts, should the first chart's 6m numbers have an inch taken away or should the second chart...
G'day everyone, I have a question on insulated wire and Flexweave! In my Hexbeam Kit it states #14 ga.pvc ins.Flexweave wire. In the Flexweave it has 168...
look for 14 ga speaker wire wire coating or what is call zip cord for lamps you can get it as low voltage cord for yard liteing it is almost the same 14 awg is...
I think you have to get it from here ... http://www.thewireman.com/antennap.html -Jim/ND6P To: hex-beam@yahoogroups.com From: vk4oc@... Date: Sun, 7...
Hi Jim Many thanks for the link to the wireman. That's seems to be the right place to pick up Flexweave and lots of other bits of wires for our hexbeams. 73 ...
Well, we finally enjoyed a break in the weather and the Hex went up yesterday -- with the thru-bolt, I might add ;). The 20 meter elements are up about 48...
All good thoughts. After a weekend working with the BBHB and MaxGain spreaders I tend to appreciate Phil's succinct answer best... "bent." John, kx4o...
... "Bent" haha! I used Fibreglass Telescopic Poles from a fishing tackle supplier for my BB Hex Beam. These are commonly referred to as "Squid Poles". Wall...
Hello friends, Since January 2009, I have been chasing WAS T.P.A. with my HX-5Bi and I reached a goal today by working ND on SSB. This is very tough award from...
Hi Shin Congrateulations for achiving this award. When you have the right type of antenna (Hexbeam) you can talk to the world. It's great feeling of conquering...
Excellent Shin. Congrats on the award. Still working on my TPA, 11 contacts remaining. 73 Steve W6ONV Sent from my Verizon Wireless BlackBerry ... From: Makoto...
