No idea, but that is a rule. When you redesign Yagi operating frequency element lengths and spacing must be corrected. otherwise you will have low SWR, but antenna performance will be worse.

Non ne ho idea, ma questa è una regola. Quando si ridisegna la frequenza operativa Yagi, le lunghezze e la spaziatura degli elementi devono essere corrette. altrimenti avrai SWR basso, ma le prestazioni dell'antenna saranno peggiori.

Boom con attacchi diversi per variare la distanza tra gli elementi e manuale per porzioni di bande diverse con misure pre tarate. Questo sarebbe un modo .
Coax question. I just put up a new Sirio monsoon base antenna with 100’ of rg8u coax testing with myMFJ antenna analyzer shows 1.4 swr at 26.965mhz and a 1.1 at 27.405 mhz . When I checked the ohms it’s steady a 30 ohms across the entire bandwidth.
