27mhz range increase with CB stuff????
 

i bought a 1/24 scale tank so i could mount a wireless night vision camera so i could drive it around the back yard at night and see whats been running around out backyard at night. and then shoot BBs at it! the range of the tank is about 200 feet but we have 8 acres and no neighbors so i'd like to increase the range. I'm hoping i could use some CB equipment to extend the range significantly. i found a 25 watt amp in france for about 20 bucks

but i don't know what connections it has on it.
during my research i've found that the ideal antenna length for 27mhz is 17feet for a half wavelenth and 5/8 wavelenth is even more efficient. but those all use a COAX connection and i'm unsure hot to connect them.

If anyone has info to help me increase the range significantly with CB or any other mods i'd appriciate it
