Okay, I'll bite. Who makes antennas that won't vibrate in the wind and have
failure of the elements without using a rope?

Why use poorly designed antennas in the first place,
ropes in the elements just fixes a poor design. Sure
if you get those poorly designed antennas for free
but I wouldn´t pay money for them. Proberly designed
elements doesn´t need ropes in them.
Also with rivets it makes it difficult to dismantle
elements if you ever need to.
