1.6 Howit Works
TheTQ‐GuardianA2Aamplifiessignalsthatreachabuildingfromthenearestradiotower,andfromradiosinsidethebuildinggoingback to the
tower. This compensates for weak reception caused by distance, topography, building structure, etc. The BDAreceives the signal from
an outside antenna, amplifies that signal, and then rebroadcasts it via antenna(s) inside the building,where it can then be picked up by
radios inside. In the reverse direction, interior antennas also pick up signals coming fromradios,where
theyareamplifiedbytheBDA,andthen passedtotheexteriorantennaforrebroadcastbacktothe tower.

CHAPTER3:PLANNINGTHEINSTALLATION
3.1 InstallationOverview
Typically,aBDAinstallationfollowsthesesteps:
1. Choosea mounting location for theexterior antenna. TherecommendedYagi directional antenna is, pointed directlyat the radio
tower (line of sight). The antenna is typically mounted on the wall or roof of the side of the building with thestrongest
signal.Agrounded lightningprotector isrequired betweentheexterior antenna and theBDA.
2. Next, choose the mounting location of the interior antenna(s), being sure to take separation requirements into account.Long,
narrow spaces benefit most from directional flat‐panel antennas, while more square spaces benefit more fromomnidirectional
domeantennas.
3. ChoosewheretomounttheBDA.Thisshouldbeinasecureindoorlocation nearagroundedpowersource.
4. Mapthe cablingroute betweenthe exteriorantennaandtheBDAandbetween the BDAandinterior antennas.
5. Proceedwitha‘softinstallation’connectingcomponents withoutsecuring theirplacement untiltesting canbecompleted.
6. Poweronthe BDAandperform configuration andtestingexplainedinChapter5.
7. CompleteinstallationbysecuringtheplacementoftheBDA,antennasandothercomponents,ImportantInsta

•Theexteriorantennamustnotbeco‐locatedoroperatingin conjunctionwithanyotherantenna.
•Alwaysuseaproperlyinstalled TowerIQlightningprotectorbetweentheexteriorantennaandtheBDA.
•AlwayspowerofftheBDAbeforeworkingontheroofofthebuilding, oranywhereinclose proximitytotheexternalantenna.
•Complywithallantennaseparationrequirementstopreventsignaloscillation.
3.2 ExteriorAntenna Overview
The Yagi antenna receives and transmits signals over a focused area. It must be aimed directly (line of sight) toward the radiotower that
provides the strongest signal to the building. The exterior antenna and mast (if any) must be mounted in a
locationthatmeetsallofthefollowingcriteria:
•Bestsignalstrength.
•Notco-locatedwithotherantennasorusedinconjunctionwith otherantennas.
•Awayfromallpowerlines.
•Atleast6ft.fromlightningrodantennas.
•Atleast8in.from anyperson.

RADIOINTERFERENCE WITH RADIO TOWERS AND RESULT
INCIVILAND/ORCRIMINALPENALTIES.
Note:Youmaynotneedantennasoneveryfloorofamultistorybuilding,depending onfactorssuchasbuildingmaterial,BDAgain,etc.
3.4 AntennaSeparation
Proper antenna separation prevents signal oscillation (feedback) that can interfere with the radio tower. Separation ismeasured in a
straight line from the exterior antenna to the closest interior antenna. The closest allowable distance dependsonanumber
offactors,suchas BDA gainlevel,buildingmaterial,etc.Recommended separationdistancesare:
Amplifiergain Min.separation(ad)
40dB 5’‐6’
45dB 15’‐20’
50dB 50’
55dB 60’
65dB 75‐80’
70dB 100’
75dB 100’‐120’
80dB 120’‐180’
Vertical separation is more important than horizontal separation. If you are unable to obtain the required
separationhorizontally,tryraisingtheexteriorantenna.YoumayalsotryreducingtheBDAgainasdescribedinChapter5ofthismanual.
AntennaSafetyPrecautions:
You can mix and match dome and directional antennas as needed to obtain proper coverage throughout the building orarea where
you need to boost the signal. If you use a Yagi exterior antenna, you should normally aim it away from all
interiorantennas,regardlessofseparation,topreventoscillation.
