Yep, that's the plan. I'm replacing the last 75ft with RG11, through the conduit. The rest is above grade, so I can replace it any time easily. That should give me a few db's. Then, I'm raising the antenna another 10ft on the pole. I could go higher, but aesthetically, I'd rather not unless I absolutely need to. I'll go ahead and add the full 17ft pole, but move the antenna up 10. I can remove the 7ft at any time if the signal quality is good, or move the antenna up if forced.
So, based on my calculations &
this link, I should see these gains(lack of loss?) with the RG11:
200Mhz? band RG11 increases = 0.79db
WHAS - 11 - -2.1db
WBKO - 13 - 4.7db
WBKI - 19 - -15.2db
500Mhz band RG11 increases = 1.24db
WTVW - 28 - 9.4db
WLKY - 26 - -1.5db
600Mhz band RG11 increases = 1.37db
WKZT - 43 - -7.5db
WDRB - 49 - 1.5db
WMYO - 51 - 1.3db
Bumping the antenna up another 10ft should show gains of:
WHAS - 11 - -2.1db
+3.2db
WBKO - 13 - 4.7db
+1.5db
WBKI - 19 - -15.2db
+1.0db
WTVW - 28 - 9.4db
+0.8db
WLKY - 26 - -1.5db
+0.4db
WKZT - 43 - -7.5db
+3.2db
WDRB - 49 - 1.5db
+3.5db
WMYO - 51 - 1.3db
+3.4db
I have one unnecessary splice in the RG6 up the antenna, due to the crimping issue, that I could remove. That should pick up between 0.2db-1.0db from what I've read.
Every little bit will help.
