1. Maybe there will be a competition, but only regulator knows when. In my opinion to enter in MUX5 is easy, if you are a local TV company (those 2 empty TV channels aka "tests" are reserved to local TVs), but Pidbuzh won't ever have such TV company....maybe someone from Truskavez or Drogobuch, but it's not very realistic. Ex BankTV, in my opinion is reserved to some goverment TV, so no competition for this place. Xsports...i don't know, i never heard that some TV company is happy to buy that license (yes, you can change TV company without making competition, and it already happend in ukrainian DVB-T2).
2.No there are no specifics.
3.There is only one antenna system for all DVB-T2 MUXes. 36 TV channel migh be "dirty" or amplifier is working with less power.

Ok thank you. I must correct my antenna or wait for analog TV off at yours country and improving signal by change antenna system at the transmitter on Підбуж (Дрогобицького району), гора Магура.

Currently you have maximum capacity (kW) on all transmitters in the country as provided for in the GE06? Nothing is known of the possibility to increase the power of your transmitter after switching off of analogue television in you?

this is 200w of transmitter, max permitted erp by GE06 is 760w

200w of transmitter + 7.5 db of antenna give you maximum 1124w
http://www.csgnetwork.com/antennaecalc.html
but you have to decrease by summator lose and cable lose

currently maximum power of transmitters, expressed in rms, is provided by regulator. maximum erp power (that i guess you know what is mean) is from itu files.
THERE ARE NO PLANS TO INCREASE TX POWER AFTER SWITCH OFF! I cannot talk about possibilities, there is always a possibility to increase.

1. So now the power from transmitter Підбуж (Дрогобицького району), гора Магура for all MUX is 1.124 kW - without decrease by summator lose and cable lose ?
2. Wheather 200 RMS = 200 W ?
3. "currently maximum power of transmitters, expressed in rms, is provided by regulator." - By Ukrainian regulator ?
4. "maximum erp power (that i guess you know what is mean) is from itu files." ERP is more importantly and will enter into force after turning off analogue TV ?

To sum up what the current power MUX with this transmitter (kW)? And what will this power (kW) after turning off analogue television and in subsequent years?

1.Yes
2.I didn't understand your question
3. Yes, by ukrainian regulator
4.I didn't understand your question. Hw, rms license provided by ukrainian regulator is main rule, not erp from itu.

please, read this
https://en.wikipedia.org/wiki/Effective_radiated_power
i'm quit sure that T2 on Pidbuzh TX tower is near to maximum ERP (if you consider all loss)
you can calculate it yourself here http://www.csgnetwork.com/antennaecalc.html

Ok I understand now. Thank you. I think that the power 1.124 kW is the most powerful for this transmitter ? And that this power will be after switch off analogue TV ?


760 W ERP how much is to kW ?

it is the most powerfull for this transmitter+this antenna configuration. it will be 1.124 kW

760w is 0.76kW

DVB-T(2)

Ok I ask you because I thought, that ERP is otherwise converted to kW.
So if 1.124 kW is the most powerfull for this transmitter and will be the so only way to increase the range of the transmitter will be antenna configuration.

I thank you so much for answer and patience. Regards.

Next tentative switch-off date is 30/06/2017.
and it should be final date, because a lot of frequences, that are used for analog TV, should be prepared for LTE auction in the end of 2017
