Pole and aerial rotator advice

Post by yagiman »

Would a two metre fibre glass pole
And a Jebsee A R 303 aerial rotator be safe on a chimney stack

Depends how big an antenna you are planning to put up.
Its all down to windloading and rotational torque applied against the rotator.
A Cheap TV type rotator will struggle with a big beam antenna in gales you have to plan for overkill really.
Here is a picture of my VHF/UHF/SHF antenna set up. They have been up for 15years or so, infact I am planning to replace the lashing wires as they are the weak link now. The bracket you see is one of 2 which helps to spread the load on the chimney stack.

When we recently had those 70MPH gales, I was worried, but I just turned them into the direction of the wind and they survived.
Phew!
Once summer is here I plan to refurbish the set up.
Again overkill on brackets and lashing kits and Rotator is a must, as we have no control over mother nature!

That is a differnt problem to your original question.
I have no way of knowing if your coax is faulty.
The Jebsee ar303 is only for lightweight antennas.
As for a fibreglass pole it has to be really thick walled 6mm or so, as it has to withstand the twisting torque applied to it.
Personally I would stick to a metal pole better safe than sorry.

You still havent said what antenna you are rotating.
A picture would be better, so we can see what your installation looks like.
A big 27MHz yagi has a lot more torque applied to the pole on the initial moment to get it rotating, and when you then stop the rotating the torque is applied again trying to stop it from turning, I dont think that rotator has any internal braking mechanism to stop the rotation, I think a fibreglass pole would start to split and crack.
Obviously these are just my opinions based on past experience of using rotators.
Your milage may vary.
