Basicly, yes. but a yagi or two will far outshine that..
More than just your home station is important here too..
About the best you can hope for on your mobile setup for 10 meters is
a quarter wave antenna. A very poor antenna for ground wave (which is
the type of prop you will be using up to 60 miles) It naturally has a high angle of radiation.
High gain 2 meter antennas have the radiation kind of compressed from the top if you can picture that forcing the radiation to be "lower-angle" thats what makes gain on a vertical antenna.
Look at some of Diamonds high gain mobile antenna for 2 meters or dual-band usage just to get an idea of how much gain you can come up with using some of these "co-linear" type of antennas.
I have what they used to call the SG2000 2 meter antenna, used to run it in the center of my Honda Civic roof and that would talk for miles.They call it a 7/8 wave antenna.Hears like crazy too.
On my wifes car we run the SG7900 I think it's called. 7/8 wave on 2m and
5/8wave times 3 (co-linear) on the 440 band. Also an awesome antenna performance wize. Not really as happy with the way it's built though duribility wize..
If I remember right these 2 antennas will run nearly 150 watts. (don't quote me on that one)
We live on one of the highest hills in this part of the state so we get really good range from our system even though what I'm using now is just an old
Cushcraft ARX-2B not too high off the ground. Cant wait to get a big system up and working again..
We are a 3 ham family here, so that is why we needed both vertical and
horizontal polarity. For the mobiles, and love to work some weak-signal
Get your home station antenna as high as possable, and use the best feedline
you can find as loss can be a big problem at VHF frequencies. Keep the feedline run as short as possable also.
There, probably way more than you wanted to know...hi
p.s. Not trying to say that 75 watts is'nt a good power level. 1.8db is an improvement. Just wanted to show you that
the improvement is not quite what an amp can do. Also as your station grows most amps out there do not offer inputs
