Ham Radio Antenna Twinlead, Balanced & Shielded, 4-kw, 100-ft. Rare Amp Supply

This is a rare, no longer available, one-hundred foot length of HIGH POWER (4-KW) AMP SUPPLY COMPANY NO. A-132-S BALANCED AND SHIELDED 150 Ohm TWINLEAD feed line.

My hope was to replace my open wire line with this SHIELDED twin-lead. Unfortunately at that time I underwent several surgeries that put my hobby on hold for extended years and limited my ability to make the replacement.

To my knowledge this unusual product is no longer available and I have seen no equivalent substitutes, so this is a rare opportunity for situations needing higher power shielded and balanced twinlead. Please note that especially for multi-band antennas, impedance matching antenna tuners are usually necessary in order to tame SWR and RF voltages on feed lines in spite of their high specs.

The AMP SUPPLY STATED SPECS FOR THIS LINE ARE AS FOLLOWS: 4.5 KW PEP; 150-OHM IMPEDANCE; 1.12 dB LOSS AT 100 MHz PER 100 FEET. 84 VELOCITY FACTOR; 13 GA.

The cross-section dimensions of the line measure approx.
