Helloooo,

Father is being EXTREMELY strict - decided to mount on existing TV antenna pole, which is out of line of sight because of one or two trees or even a few branches. My question, will there be too much signal loss from a 25dBi antenna (to another 25dBi antenna) through said tress over a distance of about a kilometre?

Network card generates 15dbm if that's useful.

its a case of try and see. trees tend to block the signal a lot more when wet.

battery operated chainsaw, could be of use on a dark night.

It should work OK in dry weather Growly, but you may possibly get some dropped connections in wet and windy weather.

All you can do is try it, but with 25dbi at each end you should be OK. Keep the coax as short as practicable and use the highest quality low-loss you can find.

Remind your father that your respective roles may reverse in years to come, when he is in his dotage, and he wouldn't want you to be harbouring festering grievances over antenna installations. You might refuse to let him recharge his electric wheel chair.:D

Cheers

HAHAHAHAHAHA!!! Will do!

Thanks for the advice - may have to give a bit of a hint to neighbours...
