[amsat-bb] Traveling with HT and Beam Antenna

[jim at k6ccc.org]

Someone does not understand that distance makes a huge difference in received signal strength.  It would take very little transmit power on board the aircraft to interfere with an ILS.  Even as an aircraft is about to land, the legitimate ILS transmit antennas are a couple miles away (they are normally just off the departure end of the runway, so for a 10,000 to 12,000 foot runway (common for major airline terminals), they are over two miles away).

Uh oh.

Here's the interesting part:

"They write that the attack could also be carried out from within the
aircraft, but the requirements for a strong signal and thus large power
amplifier and directional antenna would still be required, making the
operation too suspicious to carry out onboard."
