Ronard also makes a 10 foot tripod mount.

So with a 3 or 5 foot mount on a single level house , that would put the antenna at about 25 feet above ground , and with a 10 foot mount and a mast , that would put the antenna at about 35 foot above ground. The reference point of your reception situation is WOCK. To lift the NM number above 9 NM(dB) , with higher antenna height , into the double digits NM , will be good.
