Hello Iam Charly OE3KLU from Vienna Austria ->
I run many Ham Repeaters Digis Gates and about
one Year ago i started with 1st. Austrian 10m Beacon
OE3XAC on 28.188 Mhz (coordinated) now iam ready
with an 6m Beacon ( Call also OE3XAC on 50.066 Mhz )
but iam searching for an good Antenna for my 6m Beacon
locaton is on a Tower about 750m ASL and in winter there
can be many snow and high Winds so lil Antennas dont overlive ...

had a 6m Big wheel in my mind (wimo) but it looks not good for
this location ... any help or info is welcome !

Beacon Page :


Thanks de Charly OE3KLU

PS: Tower is our own ...

The WIMO Big Wheel is really very sturdy. There's a close-up of the hub here:

Hi Charly, Nevada have provided several ruggedized antennas for beacon use on behalf of UKSMG. If you drop an email to Mike G3SED at Nevada I am sure he will be able to assist you. Mike is also a keen 6m dxer There is a link to Nevada on our sponsors section to the left of this message. Good luck, Trev

I am planning new antenna for JX7SIX but its hard to find anything that can survive more than a year.
I am very sure that the Wimo antenna would only last a few months due to extreme iceing and extreme gusting wind.
Nevada kindly made a rugged vertical whip antenna for JX7SIX a few years ago but unfortunately it broke in half later on.


The longest antenna on the picture is the one that broke in half...

Hello Per !

Nice to read from You after some time - okay i have NOT so Big ICE and WINDs like You but for a Big Wheel its too much ...

With Your Antenna i think i can overlive some time ...

If You Know Kathrein comercial antennas - all 2m types
i destroy over a winter period ....

See some Procom Antennas on your Pic - cant they made a 6m Antenna for You ? too $$$ ?

Greeting de Charly OE3KLU

I am sure the Nevada antennas are very good. The problem is when the antennas are covered in 20-30cm of ice and you have extreme gusts of wind. I remember JX3EX and I went up to the QTH of JX7SIX. When JX3EX opened the door, the door went wide open in milliseconds and TJ flew trough the air
The wind is accumulated from the bottom of the volcano and abt 200M up where all the the force is unleached on the top.

Even the Procom antennas do break, but only the long ones...

I made a dipole of 4mm stainless guy wires, but then the balun was destroyed by melting and freezing ice...
Not so easy get repairs done when you depend on non-hams doing the job for free.

Wish you good luck Charly, I have a recording on my website with OE3KLU calling JX7DFA on six...

Guys, I am building many of the new LFA Yagi's at the moment in order to prove designs for commercial companies which will then sell them. I have been building some very sturdy versions too. I am happy to provide a Yagi antenna for these locations free of charge if you can cover shipping costs. Just let me know the sizes you want and I will make something to stand the elements.

@ TREV G3ZYY - I got this from Mike@Nevada ->

Hello Charly

Thank you for your E mail regarding Beacon Antennas for 6 metres.



Unfortunately my antenna manufacture for these antennas has retired and I am now unable to supply any further 6 metre beacon antennas.



I do wish you success in finding a suitable antenna and apologise that I cannot help in this case.



73’s

Mike G3SED

Thanks de Charly OE3KLU
