Since it became a reality just before World War II, terrestrial microwave has improved in systems and equipments, but with the improvements have come higher costs. Television microwave costs are so high because users are demanding more capability, land prices have increased, operating costs are higher, and there is frequency congestion along many systems. The rate for television microwave service may be as low as $27.50 per mile for the so-called "ETV Tariff," or as high as $90.00 per mile for the tariff 260 used by most commercial stations and networks. There are instances where the television broadcaster or system user can do his own microwave portions to his advantage, but this is not true in all situations. When microwave needs get to multiple channels, several relays, or requires special performance conditions, the user should consider leasing the service from qualified carriers rather than attempting to do it himself. The user can minimize his costs by acquainting himself with the possibilities and by making wise choices. (MF)
