Hi all,
Here is the issue I'm facing about my small
home installed AM transmitter.
I use (try to use) a SSTran AMT3000 AM transmiter in my home
to be received by most of my vintage radios all around the house.
The AMT3000 original antenna is a 9 feet small wire
connected to the transmitter through an RCA type connector.
-> Even when very carefully grounded,
Very inefficient transmission no matter how you place it ..
You need to place the receiving radio close to the transmitter
and even doing so you don't get a nice clean signal
but a week one with static noise.
Here are the limitations I face and the reason for this post:
- I don't have the space in my backyard to mount
a big antenna for my transmitter
- I don't have the vertical space in my house neither for any antenna
(8 feet high ceiling)
- I need to place the final antenna -> horizontaly <- at the
ceiling of my cellar
- My cellar's ceiling dimension is 28' x 15' (usable space)
Clarifications here:
I'm not located in USA but in a rural part
of Quebec City, Canada.
and my transmitter's frequency will be 1280khz.
Here is what I'm considering as options:
- Ad a stronger transmitter like this one:
RFsource AM Power Amplifier Pallet PM62FDC
between the AMT3000 output and the final antenna (matching both to 50ohms)
I know this 60watter is overkill but ok for me.
This will permit some power loss in the process but
still have great transmitting power.
- Use a horizontaly mounted zizag type of antenna (1/4 or 1/8 wavelenght)
- Use a horizontaly mounted straight antenna (1/4 or 1/8 wavelenght)
- Grounded transmitter through house copper pipings
I need your precious expertise on what would be
the best working setup for my limitations..
Thanks
