Hope someone wiser than me can help me on this.
I am wanting to build a 3 element Yagi to track my hounds tracking collar with my Icom R20 . The collar is 218 mhz. I am wanting to build something similar to this tape measure yagi . http://home.att.net/~jleggio/projects/rdf/tape_bm.htm
I found a yagi calculator and it generated the dimensions and spacing for 218 mhz. Will the plans for the "tape measure" yagi work if I modify the element length and spacing to match 218 ?
I wasn't sure if the hairpin match would work at a different frequency? The website said the spacing between the driven elements is what adjusts the SWR . Will it hurt the scanner if my SWR is high since I have no way of checking it ? I assume no since I am only recieving
Thanks for any help
