I just replaced an H20-100 with an H21-200 to gain the network connection (the H20-100 did not have an Ethernet port). Unfortunately what I have found is that the RF range of the H21-200 is significantly less than what I was getting from the H20-100. I was getting close to 100 ft with the H20-100 and I am now getting less than 40 ft with the H21-200 and it is in the exact same location as I had the H20-100. Are there any HD receivers (I do not want or need a DVR in this location) that have an Ethernet port and comparable RF range to the H20-100? I think what makes the difference is the ability to attach an external RF antenna (the HR20-100 has that capability but the H21-200 has an internal RF antenna).
