<SOS>DIY TV Antenna booster
« on: October 24, 2011, 02:11:12 PM »
Mga sir, patulong po/pa-share po  kung may design kayo ng antenna booster, ung signal na nasasagap ng TV ay:

*mahina, may picture naman po sya kaya lang malabo.
*hindi stable ung signal, nawawala po sya
*minsan naman, may picture nga, wala namang sound
*ung location, mabundok,ehe..

>>pero posible naman pong gawan ng antenna booster db? may nasasagap parin namang signal, ang kailangan ko lang po eh ung configuration ng gagawing booster. Sana po ay may maisuggest at alam ko po na meron, dahil ilan beses na din akong natulungan ng mga taga-ELAB, magigilas talaga!! ;D

Thanks in advance! :D

kung ang haba ng kable mo ay less than 10 meters, posibleng walang maitulong ang booster. karamihan kasi ng TV ngayon very high gain na ang Tuner kaya 'di na kailangan ng amplifier sa labas.

makakatulong lang ang booster kung mahaba 'yung kable at sa may antenna side siya ikakabit.

kung maigsi ang kable, pwedeng may matulong, pero very marginal lang ang improvements. 'di na katulad nung araw sa mga lumang TV na meron talagang mga nadadagdag na stations. dito sa bahay wala na kaming booster pero nasasagap ko 'yung galing Pampanga kung itatapat talaga (36 and 46 IIRC).

mas maganda mag-design na lang ng high gain antenna. mas malaki kasi ang improvement kapag sa antenna dinale.

gumawa ng high gain antenna. 'yan 'yung pinakamagandang gawin. similar sa mga satellite dish, very high gain antenna ang gamit. meron din kasing limit ang amplification sa noise floor. kung malapit na talaga sa noise floor 'yung signal, kahit anong amplification pa ang gawin, noisy pa rin ang output signal.

Bili na lang ng ganitong high gain active outdoor antenna sa cdr-king.    Actually matagal na yang antenna na  yan, mga 10 years ago pa ako nakakakita ng ganyang antenna ....  finally the chinese also decided to clone that antenna .... hehehe lahat yata kino clone na nila  .... sabagay matagal na siguro expired yung international patent niyan.

PX antenna booster 400 petot lang. tested and used ko na itong brand for many years na. madami na din akong kinabitan dun sa amin.
kadalasan lang nasisira yung transformer..24vac secondary.

yup dami niyan, 'yan may na-post na si sir alyas. 'yun nga lang pakonti na nang pakonti ang gumagawa niyan in favor of the very low gain Baron Antenna, mas mura kasing gawin, maliit lang, at mas mabenta (mahirap kasing i-align 'yung high gain antennas).

'yung UHF antenna dito sa bahay is 21-element dual Yagi, Corner Reflector (MASPRO). ewan ko kung saan 'yun nakuha or nabili ng tatay ko dati, pero  famous siya during the old days na wala pang mga cable companies at most hotels uses MATV systems. antenna alone can get channels from Baguio repeaters, at 'yun nga, nakikita ko rin dito (Manila area, Tondo II) 'yung 36 at 46 ng Pampanga, including channels 30 and 32 (from Nueva Ecija naman ata 'to) tapos 34 from Bulacan. kapag sinindi ngayon 'yung Booster na kasama nun, nasa-sasturate 'yung Tuner ng mga TV, lalong lumalabo.

ang maganda lang sa px antenna booster kung masira madaling troubleshoot. dalawa lang na transistor eh, and can be replaced by 9015 locally available for only 4petot.

try mo baron extended range antenna. 15-20 meters rg-6 japan original.

ganyan lagi gamit ko. kahit mapa uhf at vhf vlf. ok sya.

uso paba yung booster??
meron din nabibiling channel selector kung saan malakas sya sumagap ng signal.
gumagamit ako non kapag japan surplus yung tv..  :)

minsan kc nasa television nalang kung malinaw yung reception nya diba?

sanyo compare sa panasonic.. mas malakas sumagap ng signal ang panasonic.

^ yup, naka-depende sa internal circuit ng tuner. actually, meron akong na-encounter na Sony na nahihirapan sa may Pampanga area, lumalabo 'yung 2 at 4 dahil merong channel 3 na nasasagap, though sa ibang TV na gamit namin dati (Sharp at Plardin), wala naman 'yung ganung problem.

uso ang booster ngayon sa pag-split ng cable. ;D

i hate spliting cable para sa isa pang tv. kung analog tv.

kung grounded yung isang tv damay yung isa. kung manonood ka ng dvd sa isang tv damay reception ng isang tv.  :(

mas gugustuhin ko pa magtayo ng isa pang antenna para sa isang tv.. :)

naku hindi sir, meron lang kaming project dati na sa Pampanga kailangan i-test.
