Questions about this item

How do I connect the internal power cable to my HF transceiver for the 5-30MHz loop antenna?

Route the cable from the antenna's power input to the transceiver's designated DC power jack, ensuring correct polarity before tightening the connector to avoid intermittent contact.

Will the coaxial feedline or tuning capacitor need periodic replacement with 20W use?

The coaxial feedline and variable capacitor are rated for continuous 20W operation; inspect the capacitor for dust annually and replace the feedline only if the braid shows corrosion or the dielectric degrades.
