Kits include everything you need to construct a completed antenna, minus feed system or remote antenna switching unit.
Element wires are intentionally cut long to allow extra length for making terminations. Loop lengths are determined by pre-drilled holes in spreader arms. Simply lace the wires, pull taught and terminate. Full wave HF loops are very easy to make and will tune perfectly using our proven dimensions for each band with nice operational bandwidth.
A tuner typically isn’t required except of the upper end of the 10m band (typ. 3:1).
10/12 and 15m require a 75Ω matching section, whereas 17 and 20m can be direct fed with 50Ω coax. Pre-made match/patch cables can be found on the Parts and Accessories page.
