Guys, i am trying to make a boat with air-propellers.
I have to use a cheap car transmitter-receiver . which is 40mhz and transmitter is only 3v.
Its range is 20m around. i badly need to increase the effective range.
I am using a good pair of antenna. please give advice/links/tips/any-site-to-discuss-about-it to increase the range.
Any means? like increase transmitter signal strength , receiver sensitivity . i cant use yagi or disc antenna.
plz
