Assemble the mast and insert into the tuning unit (photo 3)\u003c\/p\u003e\n\u003cp\u003e2. Uncoil the LMR400 outer loop, and carefully determine the center. Attach the center to the top of the mast by pressing into the slot, and form the LMR400 into a loop.\u003c\/p\u003e\n\u003cp\u003e3. Plug the PL239 connectors into the tuning unit, and tighten. Hold the LMR400 in position so the connector can be tightened all the way in.\u003c\/p\u003e\n\u003cp\u003e4. Now you should have something looking like photo 4.\u003c\/p\u003e\n\u003cp\u003e5. Place the inner loop top into the slot at the top of the mast, centered.\u003c\/p\u003e\n\u003cp\u003e6. Attach the small inner loop via the two clips to the outer loop, as shown in photo 5.\u003c\/p\u003e\n\u003cp\u003e7. Put the three legs together, and push the top end into the angled holes provided in the underside of the tuning unit. Note: the two pieces are held together by the weight of the antenna above, so during assembly you have to make sure you provide support so they don't separate.\u003c\/p\u003e\n\u003cp\u003e8. Now you have a complete Magnetic Loop, as shown in photo 6. Connect to the transceiver.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eTuning the Antenna\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eFor UHF\/VHF, tuning is by adjusting the spacing on the clips holding the inner loop to the outer loop. For HF, the tuning rod (see photo 2) is used. Slowly turn the rod, looking for the place where the background noise in your receiver gets much louder. Note this position of the rod: this position is for the band you are using, so you can move to this position quickly the next time. Now, carefully adjust for maximum noise in the receiver. If you have a tuning mode, or an SWR meter, after you have found the maximum background noise point, you can then turn on the transmitter in a low power mode, and make finer adjustments with the tuning rod via lower SWR.\u003c\/p\u003e\n\u003cp\u003eSpecifications, prices, and descriptions are subject to change without notice.\u003c\/p\u003e","brand":"PreppComm","offers":[{"title":"Default Title","offer_id":42585616646203,"sku":"sku-50828987924648","price":427.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0617\/8950\/3547\/files\/preppcomm-antennas-mmx-lifeline-with-preppcomm-magloop-antenna-41038625079464.png?v=1761852866","url":"https:\/\/operationgobag.com\/products\/preppcomm-magnetic-loop-antenna","provider":"Operation Go Bag","version":"1.0","type":"link"}
