i'm studying for the general exam. I plan on getting the icom 7410 but this is already gonna break the bank for me. what would be a good antenna to get that is decent for worldwide contacts but is cheap and doesn't require a tower?

G5RV and off-center-fed dipole (OCFD) are popular multiband wire antennas.

You just need two trees to hang it between.

Both are also simple to build yourself.

a quick question

on the 7410, it says the radio comes with a built in tuner. does that mean i don't need to buy a separate tuner? i'm asking because i don't know if internal tuners are as good as externals.

The built in tuner usually works acrossa a limited range, like 3:1 or 5:1 SWR at maximum. A dedicated tuner is usually much more versatile.

And can include various other goodies, like built in 1:9 balun for using wire antennas and so on.

That's my experience with built in tuners. But I mostly use my MFJ–945E and LDG AT-200ProII.

But in general, I rarely needed tuners when using my OCF-D.

All the bands I used it on it was under 2:1 SWR, and in my books that's perfectly fine.

Why the IC-7410? Why not get the IC-7200, then spend the extra $600 on a power supply, stand-alone tuner, antenna(s) and coax?
