The length is critical!!!!
There are different types of antennas out there, but a 1/4 wavelength is quite common as is 1/2 wavelength. What that means is that the antenna is 1/4 or 1/2 of the length of the wave it is designed to receive. The typical formula for this type of antenna is 468 / frequency = length in feet. So 7" would be about 802 MHz for 1/2 wave.
A LONGER ANTENNA IS DESIGNED FOR LOWER FREQUENCIES. That is why we suggested that you replace your older antenna!!!
Have you ever heard of the term wavelength (or wave length)? Did you know that frequencies actually have a "size"? They are measured in meters, feet or inches. For example 300 MHz is is 1 meter or 3.28 feet in length.I also bought the RS 800 on advice here. I only wish it was a big longer as it seems kind of short to me at 7".
