In Reply to: RE: How many stations are you trying for, in how many directions and what sort of antenna are you using? posted by bob24 on November 28, 2019 at 12:51:29:
I'm 69 as of last Monday, and needed to cut down on outside volunteering.Flat-out gardening in a drought, down here in Aussie. Still have four (of 11) veggie beds to empty / fill
How open is your loft area? Do you have access to the plans and any upright beams between ceiling and roofing. ? What insulation is there in the loft? ???? I'll explain later, or you could search here on Rhombic, posted by me.
When you've got time I suggest a visit to FM Fool * and a bit of
scanner-printer work, and a copied map with NTH arrow, that you can mark your place and the sites of the DESIRED FM stations onto.Then you use a clear plastic school-kids' compass to mark in their bearings.
Only then will you know how wide an arc they all constitute. Then get a handle on each one's transmitter power, see FM FOOL*.
The one with the least / furthest will help us decide on how much GAIN the 'tenna needs to have. (*?)
NB I'd counsel that you only stick to the stations you REALLY want. And, ... this choosing might be possible IF they are also on-line so you can listen and decide!
I am VERY fortunate that I'm only interested in two stations.
https://www.abc.net.au/classic/listen-live/player/
https://artsound.fm/programs/show-schedule/ and you click on listen on-line.
The on-line sound is data reduced digital and NOT as good as analogue FM with my antenna.
My antenna is pointed at the first one which is a very strong station, and the other's repeater is ~ 0.5 miles behind and to the East, not at all strong but both are 'fully quiet.'
The top one is for FM, t'other is for DTV.
I've never overloaded an FM rcvr with that thing, and we have three FM stereo stages in the house.
ONE is a tubed front-end, and needs to be driven HARD.
Enough for now.
