Description

HYS Dual‑Band Yagi 9.5/11.5 dBi: Dual-band directional Yagi offering ~9.5 dBi to ~11.5 dBi gain over wide bands (e.g., up to 4000 MHz) — good reference for higher-gain directional. Log‑Periodic/Yagi Wide‑Band Antenna 698‑2700 MHz: A wideband Yagi/LPDA style covering a large portion of the band though not fully 698-4000 MHz; illustrates the design compromise. LPRS Yagi‑869A (869‑915 MHz) 9 Element: Narrow-band Yagi (869-915 MHz) 9-element; shows that for full 698-4000 you may need dedicated design. Pulse Electronics YA6825W Yagi 824‑896 MHz 8 dBi: Very narrow band 824-896 MHz; shows gain spec (~8 dBi) but limited band. Fibreglass Wide‑Band 698‑2700 MHz 8 dBi Antenna: Wide-band but only up to 2700 MHz; would need check up to 4000 MHz if you need that. 8 dBi Yagi Antenna 400‑450 MHz: Lower band example and not relevant for 698-4000 but shows gain vs frequency trade-offs.
