Ok so which antenna do we commonly use with our tx/rx?? SMA or RP-SMA??

if it has nothing to do with signal. u can buy any one of those and in case u need to change, change the adapter    There are convertors  available SMA female to RP-SMA female, same in male

hmm cool but which one is the commonly used?? with SMA connectors or RP-SMA?

And do these differ with cloverleaf antennas??

Generally most FPV Tx/Rx will have normal SMA connectors, whereas wifi applications uses RP-SMA

i think this is a clover leaf antenna, coz only in cloverleaf u can Right and Left hand circular polarization. I saw some radiation pattern of these antenna. Its really Gud 

So cloverleaf antennas or the HK antennas both are same?? no difference? right?

yeah you could see that in the description

Clover (TX) weight: 7.7g
Skew (RX) Weight: 8.6g

These one have  3 lobe and 4 lobe one in each 

Thanks brother

Most welcome 

So i will try to get those antennas in my store, trying to find right supplier now

All the best for ur business 

Satya bro these antennas are CP(circular polarized), they have ability to reduce multipath signals.
CL = Clover Leaf is for vtx and has 3 lobes
SPW = Skew Planer Wheel is for vrx and has 4 lobes.
If you are planning to stock RC305 setup then RP-SMA antennas will work without any additional connector as said by Deepak.

Hmmm was talking with supplier yesterday man its damn expensive (it is available at the same price as it is on HK) for me to buy just couple and test it. It will be too expensive for buyers and a loss for me. Instead i am not planning to get Clover Leaf antennas as they are not very expensive, so we can use clover leaf antennas for both TX and RX???

lil confused   

opss i mean

i am planning to get Clover Leaf antennas as they are not very expensive, so we can use clover leaf antennas for both TX and RX??? sorry

No, cloverleaf antenna are best suited for transmission and it is not for reception. Due to poor reverse polarization reflection pattern it has high loss. You can go for skew planar antennas for reception, it is similar to cloverleaf, oly difference is the lobe. skew planar has 4 lobes positioned at 90 degree apart whereas cloverleaf antennas has 3 lobes at 120 degree apart. There are many site that provide guide for DIY cloverleaf and skew planar antenna
