my radios seem that they can t power up the sectors to broadcast well what do i do to make them power up well so they can broadcast i got nanostaions picostation and 1 mikrotik board

and how do i test my sectors if they blown or ok

When you hook up the radios can you not see the broadcast? What is not happening? Most radio to sector issues can be traced to bad jumpers. Not much can be wrong with a sector. Not ruling it out, but that's the last thing I would look at, unless it has physical damage.

5 degrees beamwidth is very narrow for a sector. Are you sure that is not the problem?

The Laird 2.4GHz 120 degree sectors have 9 degree beamwidth (and 16dBi gain).

has no physical damage only been left in the rain but wasnt on it was up on my tower in the rain but there was no broadcasting when i broadcast using the nano's or the mikrotik board i get very low singal like -70dbm but the first time when i tried it on the mikrotik board i got -59dbm on one secotr and on the other i got -70dbm i got singal issues mostly i think that their is not enuff output power what do you think

I would check your jumper, radio card, or pigtail. Especially if the signal dropped. All the antenna does it take the power it is given and outputs it. It's not really like it has to have a certain power level to "power it up". If you saw a -59 and now don't you either wave a bad jumper, bad card, or bad pigtail from card to connector.

That is where i would start. Take up a new jumper. Try with existing radio. If no change swap out radio.

i think the pigtale is my issue cause all of them broke and i soldred them back on my cards are fine i will change the board aswell to test onther question i left them on the tower my sectors and it was raining heavy and lighting fell as well could it have blown up cause of the lighting the towers has a eart rod i have a digital multimeter can you use that to check if the sectors are blown or work and how do i use it cause on the sector all i can use to test is the femal connecter and nuting elese the pigtales i use to test them contuity and they use to show up readings which mde feel that there ok but seems i should get new ones my main concern is to check if the sectors are ok or blown if blown can i repair them?

I wouldn't worry about the sectors until you have exhausted everything. I have had radios take direct strikes and the sector is still okay.

i brought the sectors down todai from the tower the 6th time going up and down 24 meter the female connectors are fine when u shack it no noise showing its not broken i put my two sectors in line and a omini 3 anntenna's in line went 20 meters away and all were giving -39dbm which show's they seem ok but is their a way to try 100% to find out if they ok or not like test with a digital multi meter i can open them up just to test and re-seal them any1 got ideas on how to.

thnx j2sw for replying to my posts most appreciated

If they all work ok on the ground, I would suggest you problem may be with the cable run up the 24M tower - I assume that the radio unit is mounted at the base of the tower and the aerial at the 24M mark on the tower? If this is correct, what type of feedline (co-ax) are you using?

the radio is on the tower the coax cable is lmr 400 with pigtales on top on the tower i have power on the tower i either use the mikrotik board or i use the nanostaions as radios using a half meter sma cable

I have 2 of these sectors

I have a d-link dual router I can remove the aerials and use a SMA cable in to the sectors I have no idea if it has enough power to power up the sectors

I have one these boards

all the items I have to make a small wide area network 2 sectors at base and 2 omini at the tallest tower in Lilongwe giving coverage to at list 15 ks in the city
but my sectors are not broadcasting well and are not picking up well.

ANy chance you have a way to measure the LMR cable? See if it tests out okay. You could use a multimeter and some calculations.

all cables are tested and are fine the sma and the coaxil

do u think that the sectors are not reciving enough transmission power
