B27B Induction Coil For PAC-12 Induction Coil JPC-350 Antenna Extremely High Strength

PAC-12 and JPC-350 Antenna Loading Coil

This loading coil is intended for compatible PAC-12, JPC-7 and JPC-350 portable antenna systems. The adjustable contact selects a point on the winding so the antenna can be tuned for the intended operating setup.

Construction

• Moulded high-strength nylon coil former.
• 1.0 mm 304 stainless-steel winding.
• M10 threaded interfaces at both ends.
• Reworked manganese-steel contact spring with a positioning groove for more consistent contact.

Compatibility Notes

• Confirm the M10 mechanical connection and the antenna model before ordering.
• The achievable tuning range depends on the whip length, counterpoise, installation and selected tap position.
• This listing is for the loading coil shown; mast, whip, tripod and feed line are not included unless separately stated.

Setup

Begin at low transmit power, adjust the contact position while monitoring SWR, and verify the final match with an antenna analyzer or suitable meter before increasing power.
