最近要架设天线，为确保天线架设合法性，需要把正V750以及20米端馈添加到证上，搜遍全网没有找到答案。请问各位大佬，正v750和端馈的增益以及极化方式是？

技术问题真没有大佬吗……

@"BI1JNP"#p32233 这是端馈吗，正v您知道吗

@"BI4PMQ"#p32063 PNY商品页问答有注明，0dbd(2.15dbi)。

@"BH7HQT"#p32249 收到，那个是我昨天问的😂

都是水平极化，750的话，是2.15dbi（0dbd），端馈没看过有多少

How should I fill out the "Zheng V750 Shanghai Gains" section?

BI4PMQ

I am planning to install an antenna soon. To ensure the legal installation of the antenna, I need to add the positive V750 and 20-meter feed line to the documentation. However, I have searched extensively online but haven't found any answers. Could you please provide information on the gain and polarization type for the positive V750 and 20-meter feed line?
