For those who are keen on DIY here is how you can make a Bazooka tweeter yourself. I have been making this type of tweeter for most of my farms and I find it very effective in attracting Swiftlets especially young Swiftlets.
Secondly it would save money. The cost is less than a fraction of those Ready-made Bazookas. Best of all you could tailor the length and size according to what you want. It is very easy to make. Its only takes few minute to make one.
You could choose whatever tweeters you like to be placed inside the DIY Bazooka. For me, I would prefer a good quality tweeter.
There are few things you need, PVC pipe, PVC End cap, Tweeter and wire. There many type of PVC Pipe quality. I would prefer the thick one which has better sound rebounding.
At the end of one side cut 45dg, this is to prevent rain water from going into the pipe. As we know the DIY Bazooka is to be placed at 45dg towards the sky.
Drill holes at the bottom of the end cap for wiring and rain water to flow out during heavy down pour.
At the mouth (45dg side) use some steel wire to tight them cross over to prevent young Swiftlets from trapping inside the DIY Bazooka.
In fact I call it a dead trap for Swiftlets . Many years back a good friend of mind (Sees Seng of KT) put a DIY Bazooka at his window after couple of days he discovered few dead birds inside the pipe. He didn’t put any wire or net at the Bazooka mouth.
After completed you could use Steel plate (with holes) to hold the DIY Bazooka onto the walls. Best attach it to an Amplifier playing HYNOTIC sound and you could see birds swapping into your farm like bees.
Recommend to be used in areas of sound war especially for new and old farms if it wants to attract young birds.
Also for farms that want to attract Swiftlets from far as the sound from this DIY Bazooka could easily reach 500 meter.
Good Farming All.
