- A short video showing how I do it. Please give your tips below.
Equipment used:
SOTABEAMS Carbon-6 Mast www.sotabeams....
SOTABEAMS stake kit www.sotabeams....
Aluminium pegs www.sotabeams....
Prototype for Band Springer antenna www.sotabeams....
Just got the Carbon 6. Excellent introduction. Thank you.
👍Thanks for video Richard. Things I learned (the hard way) from doing stuff like this that may help others:
1. Wrap reflective tape around black plastic end caps - much easier to find when you drop them in long grass.
2. Cross wind wire/chord onto winders (do not loop it around winders) - makes unwinding fast and tangle free.
Regardless of trees on the summit or not, I generally use a mast. If there are trees then I set up with the mast leaning against a tree, super fast way to get your wire in the air. In that case I run it like an inverted "L" with tree branches hold the wire horizontal. If I'm using an inverted V dipole, I do the same, just lean the mast against a tree branch. Malen VE6VID
I do much the same.
Very useful video, Richard! Though I've completed 223 SOTA activations plus countless other portable operations, I understood the point of your video (some obviously didn't), and I learned a few new things from it that I will incorporate into my activations (a large percentage, actually) where I must use a mast.
Thanks Paul.
love the photography on your vids
Very useful video. I got a bothy bag which you recommended in another video and a small foldup table and chair which fit very nicely in the bothy bag if its too windy.
Your adventure videos are exellent and very helpful.
Thanks Alan - that's encouraging.
Great stuff RICHARD. Your wire winders with fig 8 winding are a must for deploying portable wire antennae. I even managed to get a 160m double on 2 winders for the 160 Club Calls contest!
That's encouraging. I have to make a 160m antenna soon.
Thank you for your trouble. Lovely little mast you have there.
Our Carbon-6 mast is very popular!
Good basic info, well done, thanks.
Hopefully the videos will improve as I get better at making them.
Great video Richard I like the tip about the wire winders .. looking forward to the next one.

Glad you took something useful from the video!
Most of my activations are on rocky ground and building up a small cairn round the base works well for an anchor. You do need a set of guys though. For those I just wrap the ends round loose rocks. Remember that 4 guys are better than 3 when it's really windy
Agreed.
Great video! Thanks, Richard.
That stake is a great idea...!
Looking forward to the video on putting up masts in windy conditions. Maybe you could do a video with the tactical mini and a bandhopper dipole? Presumably you use guylines rather than the stake support? Thanks
Yes - propbably in the summer.
i like beuse I enjoy !
No other reason is needed!
Excellent - thanks! 73, KI4ASK
Glad you enjoyed it!
Richard will you please elaborate on how you attach the wire to the pole? It looks like you slip something onto the pole and it slides down? Thanks Joy
I use a SOTABEAMS Versatile Top Insulator - designed for this application.
Very nice place, no qrm at all there :-)
Nice and quiet!
Under what circumstances would an end fed antenna be less effective than a dipole?
Read W8JI’s website for comments. There are additional problems in portable settings as the current portion of the antenna can be low (at the radio) with subsequent increased losses.
I would have thought there would be concerns about using carbon fibre around RF. Yes or No? 73, Paul, VE3EBY
Paul, while they are slightly conductive, using them like what Richard did has no effect on the antenna. Malen VE6VID
Depends. Check this out. ua-cam.com/video/idx1zdmeIOs/v-deo.html ...also see the follow-up video.
hI Richard - just discovered this - have the Bandspringer (final model) care to give some guidelines as to how long the counterpoises should be ? my 817+ldg does not seem to be able to tune well...
thank you
It's not normally very critical.
Nice video ! The antenna wire is made from 2 pieces conected and the conection points is put on the top of the pole? YO8XCM
It allows the length of wire to be altered.
Just got the Band Springer Midi, How does it connect to my ft-817? all there is, is a few bannana plugs?!
Nevermind, I found the adapter swimming in the packing peanuts from DX engineering
The Band Springer Midi needs an antenna tuner. It's not suitable for direct connection to your radio.
Richard Newstead right right.
Hi Richard - You got rather fast over the attachment of the far end of the antenna.
Would it be good the extend the end with a string to keep it of the ground?
That's how the antenna is designed. The last few metres are cord and that ensures that the end is off the ground.
I hope this is not a dumb question, but here it goes. Don't you need a impedance transformer when you feed a wire from the end? Thanks KG7CQG
Yes, some sort of matching unit is certainly required.
@@g3cwi_Radio_Adventures Thanks very much. KG7CQG
Is that a handheld mono paddle?
Found a better angle in another video. It’s a Palm paddle. I thought you had some secret design. I might have to put my palm paddle up for trade for a Palm mono.
Thanks for this Video...one of the best ones that I've seen on portable setups. de W3LES
Thanks Lester - more coming so do subscribe!
Just out of interest, being carbon, will that pole affect the tune or radiation of an end fed wire if run up the pole as a vertical or inverted L? Thx
This particular pole will make no measurable difference. Other types may be different.
@@g3cwi_Radio_Adventures Thanks...it's yours I have, so all good there!
I befuddles me as to why so many operators insist on these "poles" when excellent trees are available. There is a hardwood tree in view that would be a vastly superior way to hang that antenna. I would have simply tossed a line high over a branch and hoisted the far end of the antenna. This would perform much, much better than the unnecessary "pole" arrangement, less parts, less cost, simple....
Tress are not often available on every peak I go to.
Plenty of sites where there are no trees for miles. As a professional engineer, I would always use a mast in preference to tree.
Not every place has trees available.
@@g3cwi_Radio_Adventures Where there are no trees, fine...no choice there :-). Where trees are -- use them; it's a better antenna option and not even close. BTW I am an Industrial Engineer; it has nothing to do with Ham Radio....which I have been in for over 40 years.
@@spencermiles963 your mast is a good option on open ground, no arguments there...
Bizarre
Why?
@@g3cwi_Radio_Adventures The first 6 seconds are bizarre. You eccentric fellow.
@@matt9852 The alternative is "wassup guys!"
@@g3cwi_Radio_Adventures haha, please no. Do it your way 👍
