When searching for RCOMTECH on Taobao, you'll find a variety of their generators, including the 5kW models. However, they are not inexpensive, so it's best to check if one suits your needs.
Previously, I bought one from them that was a 1:1 scale replica. The performance was average, and compared to other brands of the same antenna under the same conditions, the different frequencies had varying VSWR values. Perhaps it was due to my antenna installation.
However, is it really necessary for a directional antenna to operate at such high power? Directional antennas inherently cause more interference with nearby devices than antennas like DP, so they might be better suited for outdoor use. But in urban environments, even 100W could disrupt household appliances, and rice cookers could start cooking on their own.😅。My neighbor's TV seems to be developing its own consciousness.😂😂。
