satellites are not weightless. they actually aren't even floating in space. satellites are constantly falling towards the earth but because of their crazy fast speed they constantly miss the edge of the earth and can continue falling. pretty wild stuff gravity is.
Yes the body of Toshiba satellite is made with PVC , IE Poly Vinyl Chloride for less weight because of plastic as it has less weight and because of this the fuel used for the satellite will be less and it could be useful for some other reasons.

no
The Belevdere has less options than the Satellite and cost less.
For satllite communication the frequency should not be less than the critical frequency because in satellite communicaton high frequency is needed which is reflected by satellite but not by the ionosphere.

Technically, a satellite in free-fall (and orbit is a special case of "free-fall") is effectively weightless. What we call weight is the force of the RESISTANCE to gravity; I "weigh" 220 pounds because I an standing on the Earth. The satellite has its own mass, and this can be anything from "tiny" to "enormous".
The weight of a satellite can vary widely depending on its size and purpose. Typically, satellites can weigh from a few hundred pounds to several tons. Communication satellites tend to be heavier, while smaller satellites like CubeSats can weigh less than 10 kilograms.

The Sputnik satellite had a total weight of about 184 pounds (83.6 kilograms).
Some planets have less gravity or more gravity.More gravity giving you more weight and less giving you less weight.
The weight of a 340 kg satellite on Earth would be approximately 3,334 Newtons (N) since weight is calculated by multiplying the mass of the object by the acceleration due to gravity (9.81 m/s^2).
