Installing Ham Radio Antenna on Roof: Mast Height Regulations, Diamond X-510N & X-50N Options

I am planning to install an antenna on the roof in the near future.
From what I heard from my friends, if the mast on the roof is over 3m, you should report it and wait for the permit, while if your mast is below 3m, you don't have to report it anywhere.
Is what I wrote above true.
If so, can I install 2.99m without permission and on this mast a 5.2m omnidirectional antenna

Or only, for example, a 1.2 m mast and a 1.7 m antenna on it

If that's true.

This is a 299cm mast "should be legal".

Yes, most people said that the mast could be a maximum of 3m.
However, opinions on whether an antenna can be mounted on such a mast were divided
- some people say that the antenna can be a maximum of 3 m above the roof level, so if the mast is 3 m, you cannot mount the antenna on it without permission, you can only use 1.2 m and a 1.7 m antenna so that the whole thing is not exceeded 3m.
- at the same time, several people claimed that I can easily mount a 5m antenna on the mast, that only the height of the mast cannot exceed 3m because then you need to obtain permits, while the antenna can be of any length (read above 3m)

I am of this opinion too.
But it all depends if you live with the guys who oversee everything and even crap calling the guys who are talking on 172.250 MHz.
Or you live where nobody sticks their nose where they don't need it (optimistic option).

As far as I remember, a building structure (mast here) is subject to a building permit if its height exceeds 2.5 m (it must be checked in the current Construction Law). Below this height, an application is sufficient. Unfortunately, the object, based on logic (even official), is the whole, i.e. the mast with the antenna. . That's why I prefer wire antennas because they are less conspicuous and effective. And you can always explain to the nosy neighbor that it's a wifi antenna. Why is it so long? Because I, a neighbor, download long files from the net ...

If the neighbor is an IT specialist, this excuse will not work.

Hello.
Most of what is written here is "NOT TRUE". It all depends on the administrator or owner of the building. Without his consent, you do not have the right to mount any antenna, including satellite, terrestrial TV and especially to put up some masts.

Edit:
Post col. c2h5oh , dispelled any statements you made about this problem.

Please read and then consider your statements.

Let us distinguish between two consent. The first is the consent of the roof manager (and the rest of the building) for the antenna installation. The topic is eliminated when we ourselves are. If not - then there are negotiations (with the manager: owner, cooperative or housing association) - and this topic has been raised many times. The second (even more important) is the consent of the local Building Supervision Authority to perform the works. The Construction Law specifies in detail which construction works and changes in a building structure or its part are subject to the notification of works, and for which a building permit must be applied for. An antenna mast is such a structure - regardless of whether it is on the roof or on the ground. Of course, let's not go to extremes - you do not need such procedures for a meter-high pipe by the chimney, but for something larger ...
In the nearest poviat Construction Department (starosty or in the district town hall) they will also tell you which receipts and consents must be collected for the installation. Of course, you can bypass it all and quietly put it down - but it can get really warm, like all this - on a windy day, it will go off the roof on someone's car or head - then the Prok will definitely ask for such receipts - and it can be uninterestingly done. . Even if it falls off your private roof! Unless some informant neighbor kindly reports to PINB and sends a demolition order. And as for wifi - it's a joke, of course, although a dilettante neighbor might swallow it :D

Moderated By c2h5oh:

However, it is worth taking a look at the link from the topic above.

I even asked in and heard two versions
1. If the mast exceeds the height of 3m, it should be reported, the length of the antenna does not matter. So the mast can be 2.5 m and the antenna 5.2 m and it does not need to be reported
2, However, I agree with the second version: So if the mast is, for example, 2m long and the antenna 1.2m in total, 3.2m in total, it should be reported because the structure exceeds 3m.

However, I will not worry about it because I decided to use a 1m mast and a 1.8m antenna, I planned to buy a bigger one, but I changed my mind (I had an opportunity)

You may not get a permit to install the antenna on the roof of a building administered by the Housing Cooperative. The roofs of the buildings are covered with heat-weldable roofing felt and the company providing the covering provides a warranty for the above-mentioned covering for about 25 or 30 years Covering. In the event of approval for the installation, the Cooperative will set the conditions for the installation and present the protocol for measuring the grounding of the antenna mast.
