Perhaps true, but that would depend on individual circumstances, surroundings, environment and etc. For that matter, the current 1/4 wave antenna for 866Mhz is a 1/2 wave for 1.7Ghz. Albeit there may not be that much in that frequency spectrum but all antennas are potential antennas for other bands and the harmonics of other bands. Perhaps the addition of a filter designed for the 866Mhz band would be a helpful addition too. Or even a directional antenna (small yagi?) at 866Mhz could be a good remedy for some. Thats certainly what is used in commercial, wireless weather station operations.
In any event, I remain convinced that lengthening a receiver antenna in a "fringe area" is certainly worth a try. Its much simpler than relocating a weather station and, therefore, remains a viable option.
