TWINANTELEAK
Radio Aerial Antenna Blue Porcelain Insulators
These little blue porcelain insulators turn up from time to time and for many years no one knew what they were used for. Then one showed up on eBay in the original box, which gave a rather full explanation. It said there was a patent pending, but I could not find the patent. Perhaps a patent was not granted.

Here is the text from the flyer included with the box:
STOP THE LEAKAGE OF
YOUR AERIAL
TWINANTELEAK INSULATOR
(Patent applied for)
Radio Business Today.
The TWINANTELEAK means successful results for your
receiving set. All porcelain
insulators, once wet, absorb moisture and both porcelain insulators and glass
insulators leak when wet. This
leakage decreases the efficiency of any set.
This is not true of the TWINANTELEAK.
The TWINANTELEAK will stand up indefinitely under all
atmospheric conditions. It has been
compared and tested with a number of the best insulators on the market, the test
having been made by applying 10,000 volts at 1,000,000 cycles per second for a
period of 3 minutes. The “TWIN”
showed no change and no noticeable heat after the test while other insulators
showed definite effects of the test. The
tests made with wet insulators disclosed that there is no continuous pathway of
electricity from the aerial to the ground support when “TWIN” insulators are
used, as the underside chambers of the “TWIN” are protected from moisture,
ice and dust.
Two “TWIN” set for one aerial $1.00.
