My property slopes up hill - my house is at the lowest part and my land slopes up hill about 30' from there. I currently have an HD9032 on a 25' mast on top of this hill. Based on advice to another post of mine, I'm going to upgrade to a 91XG and a YA1713 and combine them with a CM7777 preamp.
I was going to upgrade the mast to a 40' pole, but I was playing around with the mapping feature and I'm wondering if I really should go shorter. Here's my current radar:

The most distant station that I can get a signal from is WSBK which has a NM of -14.9 but it's not watchable. Under the right conditions, I can sometimes get WGBX which has an NM of -9.8. The "weakest" station that I can regularly get is WGBH which has an NM of -5.5. That always comes in.
What I noticed on the maps is if I lowered the antenna to only 10', the signals seem stronger:

WSBK is now -11.9, WGBX is now -6.3 and WGBH is now -1.6.
I'm wondering then if that is the way to go - go with a shorter antenna? I don't understand the difference, but I'm sure someone with more knowledge can help me. FYI, I compensated for the fact that my land slopes uphill by moving the marker on the map to where the mast would actually be and changed the address to reflect that as well for the radar.
