Easy to make, and probably cheaper for you to do it, postage would cost more than the parts

Thanks Jerry!

Thank you

Hi They are called "Stauff" clamps. I got them from Industrial Hydraulics in Lawton QLD - any good hydraulics parts supplier should carry them. Or you can try a search for a retailer on their website stauff.com.au/en/help-centre/locations/line-system-partner A full parts list for the tilt base is located here qsl.net/vk4im/vertical_02.html Thanks for commenting

Thanks, much appreciated, currently building Remote tuned 43 ft vertical (Extended aluminium flagpole)@@VK4IM

Thanks for the kind words. I'd make and sell them but I think I need a better drill press LOL. Thanks for commenting. Cheers

Thank you!

Drill press has since been replaced with a "real one". The amount of times the antenna gets raised and lowered doesn't warrant an internal tube, but your comment s noted. Thank you.

Thank you. I'm glad it inspired you to make your own version. Hope it turns out they way you need.

@@VK4IM Question: Those two black mounts for attaching to the pole, are they metal of plastic for isolation between the two? What are they called if i go to the hardware store? 😀

They are plastic with metal backing for the bolts, called "Stauff" clamps and available from an Industrial Hydraulics supply house. See this page for the parts list qsl.net/vk4im/vertical_02.html

Nevermind, I see you made this one, I was looking at the Cushcraft tilt base, yours looks a lot like it.

Yes its home made and will easily hold a VHF /UHF vertical. Import costs on the DX Engineering offering was prohibitive

Thanks 👍

Better to ask for forgiveness than ask for permission. :-)

Thanks for the sub!

Resposta em português e inglês segue: (Response in Portuguese & English follow:) Amaral Asked: "VK4IM: YOUR PROJECT IS EVERYTHING I'M LOOKING FOR, THE ANTENNA IS CLOSE TO THE GROUND, NEEDS 4 RADIALS THE MAST, IS ONLY 10 MTS, DOES IT NEED BALUN? PW8BR AMARAL RONDÔNIA ABS 73: <------> Oi "Amaral" Obrigado por comentar. Minha antena tem 32 radiais, cada um com 5 metros de comprimento. No meu caso, é melhor ter radiais mais curtos do que 4 longos por causa das limitações de espaço. Você pode alimentar a antena diretamente com cabo coaxial sem balun, se quiser. Eu uso um balun 1: 1 na base da antena para evitar que o RF desça pelo coaxial - é apenas uma precaução. O balun é feito de um FT240-31 Ferrite Toroid ui=1500 e 12 voltas de RG142 50ohm (alta potência) cabo coaxial. Você pode usar RG58CU também Low Power). 73 Adam <------> Hi "Amaral" Thanks for commenting. My antenna has 32 radials, each 5 meters long.

No worries thanks for commenting.

Thanks Jay. Nothing special on the feed. Just routed it down the pillar and came in at the bottom rather than the top. Door never gets used so its not a problem. Thanks for commenting.

Thanks

Yep they work well.

My Pleasure. Thanks for commenting

Thanks for commenting. Cost was about AU$80. Most expensive part was the structural channel. Took only a few hours to make. Full details are here qsl.net/vk4im/vertical_02.html Cheers

Hi Phil. No , I've never lived in the Whitsundays. Cheers.

@@VK4IM Hi Adam, okay thanks, seems its only me then 🙂

Yes I was a sceptic until heard the difference. I rarely use the DSP function on the radio these days as I prefer the BHI. Thanks for commenting.

Thank you and thank you 👍

Thank you 😊

My pleasure. Thanks for commenting 👍

Thanks Tech Guy! The insulator blocks are called “Stauff Clamps” and are available from the better hydraulics suppliers around the place. You can get them on eBay as well but they are near double price of what you pay at a hydraulics parts supplier A full list of parts is available here qsl.net/vk4im/vertical_02.html

Funny you say that, the tourism slogan is "Beautiful one day. Perfect the next". Thanks for commenting 👍

I'll keep an ear out for you 73"s

Hi Cliff, thanks for stopping by and commenting. Long answer for a short question because the base plate is not well described or shown in the video(s). The base plate is made from some scrap aluminium about 225mm (9”) square and 6mm (¼”) thick. I drilled and tapped 8 x M8 (5/16”) threads into the plate and used stainless steel M8 hex bolts to secure the 32 ground radials 5m (16 ft) long each. This means I can have everything in place and attached the radials from the top of the base plate with a ratchet and socket. It also eliminates two things: 1. Having to somehow tighten a nut on the underside of the plate (which could work loose) and, 2. If the nut was on top of the plate, prevents bolt protrusions catching on your toe or mower or weed wacker. The way I have it, there are no protrusions only the head of the bolt is visible. The base plate is electrically connected (bolted) to the tilt mechanism with a 40mm x 40mm 1.6mm (1-1/2” x 1-1/2” x 1/16”) angle and stainless steel M8 bolts. The angle sticks out one side just enough to hold an SO-239 panel mount. The angle does not have to be strong, its only for the electrical connection and SO-239. This method ensures the coax braid is completely earthed to the radials and the post in the ground via the SO-239 and the centre pin simply goes to the radiating element via a 100mm - 150mm (4” - 6”) long fly lead. I used 2.5mm (#14) house type earth wire for this. The benefit of the SO-239 is that you can disconnect the coax when you mow. One thing: Make sure you sand or file off any anodising from the aluminium so it creates a better electrical connection where the bolts and clamps connect. The hole in the base plate is 60mm (2-3/8”) diameter cut with a hole saw, its just big enough to take the 40 x 40 (1-1/2” x 3/16”) SHS (Square Hollow Section). You could use 4 corner holes and a hacksaw to make a square hole if you don’t have a hole saw. The SHS post is about 1.8m (6 ft) into the ground - no concrete, and about 500mm (20”) above ground. This also helps with the earthing as its clamped to the tilt mechanism. You could make the post shallower or deeper but it will depend on your ground conditions. I have soft ground here and decided to to put some 4mm (1/8”) paracord guys to help stabilise it a bit in the wind. The antenna will stand by itself without issue without them though. Don’t forget to watch the construction video if you haven’t already seen it. There’s also a write up with a complete list of parts of the tilt base on my web page qsl.net/vk4im/vertical_02.html Cheers

Pretty easy to make if you have the tools and the time. And much cheaper than commercial options

Yes, it's amazing what you can press into service as a CW key. Thanks for commenting

Thank you 👍

Thank you!

Hi Max. Thanks for commenting. The "In action" vid is separate as this one was already getting pretty long. kzbin.info/www/bejne/fJezgoyXqbWIobc

The metal is structural aluminium channel. A full parts list and build instructions are located at this page. qsl.net/vk4im/vertical_02.html

Thanks 👍

It was a hot day 😉

Thanks for the kind words. This tilt base easily lifts my multiband vertical. Think DX commander style, only all out of aluminium.
