I am thinking about a newer (maybe better) HF antenna. I have now a T-11 LPA from Tennadyne. I've always had good results with hy gain and never owned an opti beam. Any thoughts on a TH-11 vs an Opti beam OB 9-5. Both offer the same bands. 10,15,20,17,12. thanks for your thoughts, Al W4ABW Northern AL.
