- Almost all Ham Radio operators need means of supporting antennas. Unless you are fortunate enough to have tress in the right places, you will need some kind of antenna mast. Peter G3OJV, covers a number of off-the-shelf options available from Waters and Stanton in the UK.

Thanks Peter I enjoyed this presentation. Not many demo’s of mast / poles about certainly not UK. My back garden… postage stamp, ☹️ so this has given me something to think about. The mast with the clamp down clips would be the one I’d have, it seems very durable.
Anyway thanks again… re educating myself about radio as it’s been ??? 27 / 28 year absence and your channel has taught me a lot. 73 💙
Glad to help. 73 Peter.
Love your videos. Thank you for taking the time to make them.
My pleasure!. 73 Peter.
Thank you for this video. As a previous person noted: Not many video covering deploying a mast for field day operations.
Explore the Blue Sky Mast systems, a company in Odessa FL. It will last 20 yrs. I've used it in the Philippines for 5 yrs and have had no rust problems. At 30 ft the system can hold 30 lbs at 20 ft. 40lbs. Made of aircraft aluminum. 2" OD. If you want 30 ft mast as for the "reconditioned " 10 meter mast system. I had a 20 meter wire moxon and a yeasu rotator on it no problem. They have a

We have them in the US, a brand called “Easy Up”. Hose clamps are a good idea for extra security!
Another option are the tripod masts used by photographers that elevate to about 10-12 feet with a base solid enough to support the weight of lights. Photography is a demanding market, so they are well-made. It's also a large market, so the sales volume keeps prices down. I picked up two at a thrift store for $10 each, but you can also find them at online outlets such as B&N Photo. They quickly set-up and are great for getting a telescoping vertical and wire radials out of the ground clutter.
A very timely video. I’m trying to determine what masts I need for different applications.
Glad it was helpful!
Have used the LMA 10m masts in the past with M0CVO Off-centre-fed dipoles. They held up against some serious winds on Skye and provided many many contacts from IoM and when we hosted G100RSGB. Great portable/temporary gear. Thanks for sharing a few alternatives Pete.
Thanks for the info! 73 Peter.
I have one of those TMF fibreglass type masts. In constant use and been going strong for over 15 years. Recommended.
Nice to hear. 73 Peter.
Very interesting thanks for sharing 😊
My HD Spiderbeam 12m mast has held up so far, knock on wood, very well for about 4 years, in central Canada, in some ludicrous weather. It is set up permanently in the back yard, and is the high end of an end fed. The tip does bend towards the matching box, but it's been a real wonder. I use a kevlar string to guy against one direction of wind, and it's also held up really well for such a small looking guage. Great video, Peter.
Many thanks. Great to hear from you. 73 Peter
I use one of the aluminium telescopics for my G5RV. I put a pulley at the top, so I can put the mast up, and then pull up the weight of the wire with a rope. That means if there's a gale coming in, I can lower the wire in seconds, without messing with all the mast clamps. I also drilled a small hole in the bottom of the bottom section, to let accumulated rain out - it's amazing how much the mast collects, which then runs down the inside of the next section down, and so on.
Many thanks for sharing. 73 Peter
Thanks for the video, good information
Cool video my friend. Just starting my journey into ham 👍
Cool 👍 Welcome to Ham Radio.73 Peter.
I use stainless steel jubilee clips. A bit harder to find but they don't rust.
Thanks for the tip.
Thanks for sharing.

Great video, many thanks! Robert K5TPC
When using hose clamps I use a strip of old cycle innertube around the pole to stop galvanic corrosion. I use stainless steel clamps. Are the GRP masts protected from UV as this will degrade the masts over time
I use silicone tubing to sheath stainless steel hose clamps. Used rubber strips with shrink tubing in the past. The silicone is much easier to work with, more durable and gives a better grip.
Good tip.
I also use the silicone tubing around the clamp. but i use the butterfly version of the clamps, no need for tools to tighten.
Interesting Peter but I'm not sure about the anchor points you mentioned. I would like to have seen this more clearly. I'm in a rented property so using concrete might be a problem.
If your a capable do it yourself person then using the technique that stiffens a sailboat's mast is a great way to have a dependable mast.
Many boat masts use a diamond shape truss along the lenght of the mast to resist the tremendous forces applied by the wind striking the sail. This truss is typically made from stranded wire cable but nylon rope could be used. Its beyond the scope of a heads-up to detail how the truss is assembled, but Google can fill in the details.
Without the diamond truss 30 or 40 feet of 2 inch PVC pipe coupled together from 10 foot lenghts would behave like a piece of spaghetti if held vertical. Once it has the diamond truss installed & resisting bending along its lenght then as some say, bob is your uncle, or good to go.
Many thanks for that info. 73 Peter.
What sort of 11 meter or hf vertical would it hold the 2nd and 3rd poles
Yes nice mast but I have just bought a 12m rascal telescopic mast and it was only £295 to put my endfed and 7 band cobweb antennas its abit like your one but a bit steadier
Enjoyed the video, could you do a “short” showing how you remove the top sections from a Spiderpole, do they pull out from the base? Thank you
Remove base cap and slide section out
WHAT ABOUT "LIGHTNING ARRESTERS"?!...... WHAT'S THE BEST WAY TO GET BETTER "CLARITY", AND AUDIBLE SOUND QUALITY, OUT OF ANY SHORT-WAVE RADIO SYSTEM???!!!!!!!!!!!...
Many thanks for this wonderful video. I am new to HF and found this to be quite educational. I noticed the top ends of the mast are plain...so how do you suggest I attach wires to the top? (say for an inverted V or other type of dipole)
I often use a hose clamp. If you are using a balun then you may be able to hose clamp it in place. Otherwise tie wraps or whatever is to hand.
@@watersstanton Thank you.
Great video as usual, thank you!
Do you think the last fibre mast would cope with a Diamond CP-6S (4.9kg / 4.5m) on top of it?...
Or would I need a heavy-duty telescopic mast?...
In advance, many thanks for your time.

The heavu duty one yes, but would need guying.
@@watersstanton Thank you! 😁👍🏻
@@watersstantonJust received the CP-6SR, 30ft telescopic mast and Stick-230...
THANK YOU for the super fast shipping. 👍🏻
Might have to wait before I assemble everything, I'll keep you posted...
Have a good weekend.

Do you have any suggestions for attaching a mast to a Sprinter door? Hating to drill holes in my new van.. I'm looking to support a screwdriver antenna such as a Yaesu ATAS or Lil Tarheel II while stationary in a park or campground
Great video. What would you suggest as a semi-permanent mast for supporting a small rotator?
It would primarily depend on what antenna you put on the rotator.
How would one support a balun or transformer for an end fed antenna using a mast? Is the tip / top section strong enough to handle the weight?
I have the balun box on the ground and have the antenna in a inverted V or the balun at the bottom of the pole like an inverted L.
Use the stronger fibreglass mast or the metalversions.
@@watersstanton I love your videos but I am trying to get a HF antenna up in a small yard her in the states. I am told that you can not use anything as a mast that is conductive for a dipole or it will interfere. But yet I see people recommending metal masts. I am confused.
Also, can I buy things in your store to support your company even in the US? Also a long video showing how to attach a dipole to a mast would be so helpful.
I have been looking at several of your videos but haven't seen a review on any of the dx commander antennas they should fit in a small garden the sound interesting as no.balun to eat up power please do a video on one of them

Hi Erik, there is a limit to how many antennas I can review. Currently I I am working on some portable antenna reviews as we go towards Spring in the northern hemisphere.
Antennas are the most important part of operating radio without them your radio is nothing
I dont think anyone in the US sells the lma?
Try MFJ
@@watersstanton I don’t think they carry metal
Cotter keys, hose clamps fail too often.
How do you use them? I am told you can not drill fiberglass or do you only mean the metal ones?
we still have 2 months until spring comes LA2VLA
Ah yes, as and so do we. But WE can't play golf at midnight in June!!
@@watersstantonNo driving ranges there ,Peter?😮
