This is a small antenna that can be made for any band similar to the AX1. Works well with Elecraft KX2 or radios with built in tuners.More details on my YouTube channel. https://youtu.be/h-48mcNdAFoTo figure out band configuration. Need to determine inductance needed. I used this calculator on the web.https://www.66pacific.com/calculators/coil-shortened-vertical-antenna-calculator.aspxOnce the Microhenry is know. I used kit and parts calculator to determine turns on the toroid.I used a t50-6 but you could experiment with others. http://toroids.info/T50-6.phpOnce I had that I added a few extra turns and used an antenna analyzer to bring the SWR down and and get as close to a 1:1 match as I could. Then the tuner would take care of the rest. These are the parts used in the build.Telescoping Antennahttps://www.amazon.com/gp/product/B07SB58JMB/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&th=1BNC for Tri-pod mounthttps://www.amazon.com/gp/product/B087BJGL8P/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1Male BNC for one side of the Coil extension and for antennahttps://www.amazon.com/gp/product/B077Y6J1Z9/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1Female BNC for Coil extension.https://www.amazon.com/dp/B077VNHM8S/ref=sspa_dk_detail_1?psc=1&pd_rd_i=B077VNHM8S&pd_rd_w=pFe7v&content-id=amzn1.sym.386c274b-4bfe-4421-9052-a1a56db557ab&pf_rd_p=386c274b-4bfe-4421-9052-a1a56db557ab&pf_rd_r=Y23N44WDH4XYPV6NPWVD&pd_rd_wg=h5CqH&pd_rd_r=5fd81775-547e-4200-bc6a-2c9873c5d35c&s=electronics&sp_csd=d2lkZ2V0TmFtZT1zcF9kZXRhaWxfdGhlbWF0aWM&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUFPN0FYQUg1M1FPVFcmZW5jcnlwdGVkSWQ9QTAwNDgwODMxQ1owRUdVUDlMRk1IJmVuY3J5cHRlZEFkSWQ9QTA3NTI2NjZKNlAyTDJKTDMzSlYmd2lkZ2V0TmFtZT1zcF9kZXRhaWxfdGhlbWF0aWMmYWN0aW9uPWNsaWNrUmVkaXJlY3QmZG9Ob3RMb2dDbGljaz10cnVlscrew is a 3mm x 10mm with a nuthttps://www.amazon.com/gp/product/B07L9MMN9K/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
