A Future Metro Manila DTTV Tower?

As the Philippines officially adopts ISDB-T as the sole digital terrestrial television (DTTV) standard, there is an important consideration about installing a DTTV transmitting antenna over the current TV tower structures owned by most TV networks in the Philippines as discussed on this blog not affiliated from the official order of the National Telecommunications Commission (NTC), where it was currently assigned a new DTTV channel suitable for most TV networks right after the conclusion of creating Implementing Rules and Regulation (IRR) in June of 2011 (but later revised momentarily by August of 2011 after reviewing a standard together with DVB-T2) to be released only in a given time of the launch of DTTV broadcasting. Since most digital terrestrial signals like ISDB-T consume less electricity than the analog radio and TV transmission, it may be susceptible to signal obstruction like high rise building and mountainous areas. Therefore the purpose of this is to have an even higher elevation in order to lead over that obstruction and widen signal coverage even at low-lying areas. Another consideration is the possible reduction of TV tower congestion uniting all DTTV channels, as mentioned at the end of paragraph in this blog.

The following table shows a possible scenario when all congested Metro Manila TV tower running on ISDB-T DTTV transmission become problematic due to obstruction of high rise buildings and mountainous areas. (See also figure above.) Note that GMA Tower of Power, RJTV Tower, and ZOE TV Tower are the only structure in order to have wider DTTV coverage over other TV tower.

Net 25

RJTV

Mountainous areas on northern part

ZOE TV

UNTV

Sonshine TV

Some open spaces free of high rise building

NBC (Aksyon TV)

Some open spaces free of high rise building

High rise building blockage in some portion of Metro Manila due to its low tower height structure, Las Piñas area due to low elevation

In that case, most households watching either CRT or LCD TV connected with ISDB-T set-top-box (STB) would encounter DTTV signal interruptions when most DTTV channels owned by various TV networks running on their own TV tower as listed above would persist. In order to remedy this problem, though mandatory, only an outdoor DTTV antenna having a 4-bay conical array and a rectangular reflector could be capable to trace DTTV signal overlapping such obstruction (see below).

As high rise building—known as skyscraper—in Metro Manila became widespread as a result of blocking all congested TV tower, one of the simple but expensive solution is to build a high rise DTTV tower similar to Tokyo Sky Tree Tower in 2011. The possible design of the proposed construction of the tower in metropolitan Philippines different from aforementioned Japanese tower structure is currently pending.

Various privately-owned TV networks in the Philippines, as well as the Philippine government, various telecommunication companies, and private real estate companies would unite together in order to construct a DTTV tower together with a Japanese partnership only with consent, spending billions of pesos to buy materials as well as equipment and labor. The construction of future DTTV tower in Metro and Mega Manila for the next two to three years, according to my own thought through possible reliable source in the coming years, would be in a portion of mountainous areas in nearby town of either in Antipolo or in Jala-Jala, Rizal, or on the ground of Metro Manila area originally planned for the construction of PAGCOR Tower.
