Default using an MFJ-941E tuner on all bands?

It depends upon what you want your radiation pattern

version of EZNEC available from eznec.com will tell you
what direction your lobes are pointing.


I tried using the demo version of EZNEC, but haven't figured it out yet.
I don't really know yet what I want my radiation pattern to be because
I've had an HF radio now for three weeks, and only a 10 meter dipole.
(tuner to be delivered this weekend). Of course I have made no contacts
on 10 meters. I tried CW on 15 meters (yes, on my 10 m dipole with no
tuner, at low power) but no one has answered. Probably because of my
slow wpm. ;-)

Anyways, I'm not sure yet what to expect as far as making contacts.
Would I have a better shot from east or west, or would I have a better
shot north and south?

Well, before I go too far off topic, I read ch. 7 from the ARRL Antenna
book, and I think the best for me as far as antennas go, is the 135 foot
dipole fed with 450 ohm window line, and it will have to go east/west
which means I might be talking to Santa this year! ;-)

So, I guess what I should have asked was, what would be the best
orientation for a dipole in New England in order to make contacts at
this time of year and at this point in the sun spot cycle.

Ok, having said all of that, I have some ideas for shorter dipoles that
can hang north/south. So there is much experimenting in my future. :-D

Busy weekend, be listening for me on cw!
