本人即将搬家，由于房屋为独栋自有的小别墅，想在楼顶架设天线，但是在网上没有查到符合条件的解决方案，想咨询一下各位大佬是如何在房顶架设天线的，是否要安装避雷针，馈线如何选择，如何将馈线延伸至室内，如何做防水处理，以及，八木天线的云台如何挑选安装调试期待各位的回复，谢谢！

架什么天线？要是短波建议直接二十米端馈，便宜好用

@"BI6NTI"#p59875 其实我原本想着装正v的，因为我的位置北方有楼群遮挡南方却很空旷（

我架的是GP，先用废弃的车位锁焊了个3×3米的十字形底座，中间立一个2米的50钢管，天线抱在上面，属于简陋方案。你要立八木又要旋转器，还是独栋，这条件不上铝塔太可惜了。如果能提供楼顶环境的照片，大家提建议会方便一点。

@"BI7BJT"#p59922 P2是为了展示地理环境

直接买跟dn50镀锌配合正v750，中间还能加根玻璃钢，注意拉好风绳

@"BD4UJA"#p59927 这个方案简单可靠，性价比最高👍

先拉个750试试水吧。一般别墅区上塔必遭投诉说有辐射

@"BG2EFX"#p59959 雀食，这边的人很naotan的，指不定哪天就来个说影响孕妇了

How to install an antenna on top of your own house

BI7BJT

I am moving soon, and since my house is a detached single-family villa, I would like to install an antenna on the roof. However, I haven't found any suitable solutions online. I would like to ask for advice from experienced individuals: how do you typically install antennas on roofs? Do you need to install lightning arrestors? What type of feedline should be chosen? How can the feedline be extended indoors? How can waterproofing be done? Also, how do you choose, install, and test a Yagi antenna (specifically an "八木" antenna)?
Looking forward to your replies, thank you!

What kind of antenna should I use? If you're using shortwave, I recommend a simple 20-meter feedline. It's inexpensive and effective.

BI7BJT

BI6NTI Actually, I was originally planning to install a full-sized antenna, because my location has buildings blocking the southern view, but is relatively open in the north.

Liridice

I'm using a GP antenna. I first welded a 3x3 meter cross-shaped base using discarded car door locks, and then installed a 2-meter diameter 50mm steel pipe in the center. The antenna is mounted on top of this. This is a very basic setup. If you want to install a Yagi antenna, a rotating feed horn, or a standalone tower, it's a shame not to use an aluminum tower. If you can provide photos of the rooftop environment, it would be helpful for everyone to offer suggestions.

Because I rarely visit the construction site, I have attached a satellite image of the site for your reference.😶

Purchase directly a DN50 galvanized pipe along with a V750, and you can also add a glass fiber tube in the middle. Be sure to properly secure the guy ropes.

This solution is simple, reliable, and offers the best value for money.👍

First, try a 750 to see how it performs. Generally, installing a tall antenna in a residential area will likely result in complaints about radiation.
