they can't be 240 m. there`re no their 3D model in Google Earth. 15 red and white sections with 6 triangular prisms in each even if 1 meter height...

I want to request these masts since long time, but I could not find any source of their height! The height of 240 metres may be correct and would be plausible for a mast radiator for 630 kHz. But as no one can offer an official source, I would not add them.

In fact even the following ways failed:

- contacting the operator of the transmitter by e-Mail
- making a request to the Romanian flight authority to add them to their list of air-traffic obstacles (where they surely belong to)

Perhaps a forumer with a Romanian e-Mail account can have success with a request in Romanian language!

I apologise for the length of this reply; I was experiencing technical difficulties with my devices. This was the reason I was unable to reply for some time. I attempted to locate the masts on official maps for aircraft obstructions, but they were incomplete. In particular, they lacked information about the height of the obstacles, which is crucial for navigation near Voinesti.
The maps I consulted were https://www.lrbb.ro/maps/VFR_Chart_ICA and https://maps.lib.utexas.edu/maps/tpc...34566_f-3a.jpg. The O_LR_2_ROMANIA.pdf and https://maps.lib.utexas.edu/maps/tpc...34566_f-3a.jpg If I may make a suggestion, I believe that if each mast section is measured to be exactly 1m, the height of the masts would be 95m.

Platform fences are visible on a few levels of the masts. I assume those are 0,9 m and they seem to be half the height of one section. So each section is 1,8 m?

I estimate the tiny mast, that's visible close to the radio station in Google Streetview, to be 27 m. Judging from the the wall on the concrete lookout tower close by, that should be 0,9 or 1 m.
If I place myself in streetview on a point that is of equal distance from the tiny mast as one of the taller masts, the tiny mast seems to be as tall as 15 sections of the taller masts. 15x1,8=27.

If this is correct, then I estimate the masts to be about 170 m tall.

The southern mast situated at 45.056345 N 25.262327 E has its outmost eastern guy anchor at 45.057516 N 25.264019 E in a distance of 185 metres.
The mast is not guyed at the top. just below. In case of an angle of the guy wire of 45 degree to the ground, its upmost guy point is in a height of 185 metres and its total height is 200 metres.

At realized guyed masts the angle of the guy wires to ground is greater than 45 degrees for the upmost guy levels in order to save space. For example at Konstantynow Radio Mast ( https://skyscraperpage.com/cities/?buildingID=46244 ) the upmost guy level was at a height of 594.3 metres, the distance of base and outmost anchor block was 417.1 metres, the height of the upmost guy anchor was 1.4 greater than the distance between mast basement and outmost guy anchor.

If the same proportions were used at Voinesti, the upmost guy level would be in a height of 264 metres and the mast may have a total height of 280 metres.

For physical reasons a mast height of half wavelength would be best and this would be for 630 kHz 238 metres. However a bit taller would be also OK and so a value between 235 metres and 250 metres would be correct.

Why are no height values for this objects published?
