Good catch! I put the dyslexic brain onto the
6.25 and read it as 2.65 . . . and indeed, the
original figure may have been a typo. But yes
indeed, an antenna 12.5" long would make a poor
transponder antenna.

DOT Outlines New Standards For The Transport Of Lithium Batteries
Air, Ground Shipments In The New Rule
The U.S. DOT has issued new standards to strengthen safety conditions for
the shipment of lithium cells and batteries. These changes, some of which
focus specifically on shipments by air, will better ensure that lithium
cells and batteries are able to withstand normal transportation conditions
and are packaged to reduce the possibility of damage that could lead to an
unsafe situation.

=9CSafety is our number one priority, and this rule provides an addit
ional
layer of protection to the shipment of lithium batteries, which we all
depend on daily to power our phones and our laptops,=9D said Transpor
tation
Secretary Anthony Foxx. =9CToday=99s standards are part of our
ongoing work to
improve safety for all travelers, including those who travel with or ship
lithium batteries.=9D
The Department's Pipeline and Hazardous Materials Safety Administration
(PHMSA) developed this rule in close coordination with the Federal Aviation
Administration (FAA). Voluntary compliance is encouraged upon publication
of the final rule; however mandatory compliance is effective six months
after publication.
The rule will also provide a greater level of consistency with
international standards, including the International Civil Aviation
Organization=99s (ICAO) Technical Instructions for the Safe Transport
of
Dangerous Goods by air. =9COur continuing efforts to harmonize U.S. H
azardous
Materials Regulations with international standards improve consistency in
procedures and terminology when shipping lithium batteries around the
globe,=9D noted PHMSA Administrator Cynthia L. Quarterman.
According to a DOT news release, the final rule will:
- Enhance packaging and hazard communication requirements for lithium
batteries transported by air;
- Replace equivalent lithium content with Watt-hours for lithium ion
cells and batteries;
- Adopt separate shipping descriptions for lithium metal batteries and
lithium ion batteries;
- Revise provisions for the transport of small and medium lithium cells
and batteries including cells and batteries packed with, or contained in
,
equipment;
- Revise the requirements for the transport of lithium batteries for
disposal or recycling;
- Harmonize the provisions for the transport of low production and
prototype lithium cells and batteries with the ICAO Technical Instructio
ns
and the International Maritime Dangerous Goods Code; and
- Adopt new provisions for the transport of damaged, defective, and
recalled lithium batteries.
PHMSA develops and enforces regulations for the safe, reliable, and
environmentally sound operation of the nation's 2.6 million mile pipeline
transportation system and the nearly one million daily shipments of
hazardous materials by land, sea, and air.
