LNA in VHF

Is there any need to LNA in VHF frequencies?(100~300 MHZ)

How we get signal from anttena and apply it to first mixer?
If we use LNA ,we pickup many unwanted noises and we can not get our signal,there are many TX that work in this band with high output power,so we have to use high power TX and signals are strong enough ,so there is not need to LNA,what is u idea?

I think it depends upon application, but with LNA you achieve better sensitivity (lower noise figure), but as you noted, bandpass filter are necessary in either case to remove out-of-band strong signals, which could end up in your intermediate frequency without it...

Insert a BPF between LNA and Mixer?
