You can passively or actively boost the strength of your transmitter. There are pros and cons to each. This is something we cover in our UAV Operator class, which you can find under the Training section of our website.
Keep in mind, however, that any modification you make to your system that is outside of the unit’s manufacturer operating specifications will void your warranty and insurance, leaving you vulnerable if an incident occurs.
The answer is irrelevant. Here’s Why. According to Flight Conditions 15 of the Transport Canada UAV Exemption, the pilot must maintain unaided (binoculars, not glasses) visual contact with the UAV at all times. That means even if you want to boost your drone to get a range of 10km or more, unless you can see it that far, it’s a violation of the UAV exemption and therefore subject to a minimum $5,000 fine.
That is a complicated answer. Are you flying recreationally or commercially? How heavy is your UAV? What class of airspace are you looking to fly in? Please remember that UAV are considered aerial vehicles, not model aircraft, and are taken very seriously. We would suggest looking under the Training section of our website and attending the UAV Operator Course.
According to General Condition 4 of the Transport Canada UAV Exemption, a recreational UAV operator must have a minimum of $100,000 in liability insurance.
