YAGI CALculator

Cushcraft A148-20T 2M, CROSS-YAGI, 10/10 ELE, 24DBI, 1KW

From the Cushcraft Ad:  A148-20T
2 Meter Hi-Lo Cross Yagi
 

Here’s the antenna that solves multi-mode problems!
 

Ten vertically polarized and ten horizontally polarized elements provide  11.1 dBi gain covering 144-148 MHz. The horizontal elements handle your  CW and SSB needs, while the vertical elements cover FM.
 

Hardware is stainless steel. Separate coax feeds allow polarization changes.  https://ameritron.cushcraftamateur.com/Product.php?productid=A148-20T
