All these lightweight designs are good for occasional VHF activators. Those who want to activate frequently on VHF are better off with a more rugged mechanical design. My first portable VHF beam was a 4 element DK7ZB with a 1 m boom. I used those plastic clamps and each of them didn’t last long. Their fit gets looser the more you use them. Especially in winter, they break easily. Hard to keep the directors in place when its windy.
In summer 2017 I built ‘5-Elli’ and I’ve been using her since. She’s a 5 element 28 Ohms DK7ZB 8,5 dBd with a 1,5 m boom, packs at < 60 cm, is less than 600 g. No tool needed to deploy or disassemble her. Good in winter when the fingers get cold and wet…
The elements are of 8 mm diameter (driven element 10 mm) and are held by electric fence wire & rope insulators which are perfect for 8x1 mm aluminium pipes. The elements consist of two halves which both have rivet nuts and one has a headless screw. So they easily screw on each other. The driven element is a little bit different, you get the picture. The brown 75 Ohms coax’s are the transmission line 28 -> 50 Ohms.
The mast mount is made of two lightweight clamps from the hydraulic supply. It didn’t fit exactly to my pole at the desired height, so I put a piece of plastic pipe in it.
If you look closely, you see the antenna is ‘hanging’, which means the boom is below the mast mount and the elements are mounted below the boom. This gives more stability to the complete system including the glass fibre pole.
5 Elli is even capable of EME.
Last autumn, 5 Elli got a sister.
The complete system including the stacking harness is less than 1,9 kg. Quite lightweight for 11,3 dBd, I think.
