The most visible tower in the Philippines is this tower of a telephone company
PLDT, the phone company and its Internet SmartBRO and cell phone towers.
This is the tower of FM broadcasting station
The tower is not freestanding but supported by stay wires.
The problem is that stay wire, ordinary wire is used a lot!
Here is another tower for FM broadcasting standing on top of the building
The antennas of the government offices, police stations, and others are mounted on poles (pipes) of nearly 20 meters long, like this one.
Here is an amateur radio VHF yagi antenna
There are about ten of them in Osamis, but they are all in bad shape, some of them have disconnected coaxial cables or antennas pointing down.
Now, the reason I did this survey was to find out how much it would cost to build a 25-meter tower by myself.
Angles sold in hardware stores

A 25-meter class freestanding tower will stand for about $300,000.
In Japan, it would be about 1 million yen.

Of course, it can't be built right away.
That's after I bought 300m2 of land behind my house for 230,000 pesos.
