If someone is tampering with it, the spider is one of the easiest to restore.

And i wouldn't be surprised if they would just destroy something more solid with more force.
If someone wants to do damage to an antenna installation, they'll find a way.
Exactly my sentiments.
If you see the picture here, someone is actually taking the trouble of climbing the ladder to the very top.
(Point to note, the antenna is mounted not where intended on the picture, but the diagonally opposite corner (closest to the airport) + least restrictive view of the horizon.)

I have RTL-SDR Tripple Filtered LNA. Eliminates Cell/Mobile signals.

Note:
The Bias-T and DC adapter in the photo are NOT supplied with the LNA. I have purchased these separately
Why did you purchase the Bias T when you yourself have made a good design? What extra feature/protection does the commercially sold Bias T have to offer?

My DIY bias-t was made usig tv splitter with F-connectors. The LNA's connectors are sma. Also having a screw terminal for DC adapter wire is convinient. This bias-t is not costly only $4.
