I'm going to add another dipole to my small antenna farm. I already have 17 and 10 meters.

Which do you like better for SSB between these two bands, if you had to pick one - 12 or 15 meters?

I'd go with 15. Lower in frequency will be open more often. More people with 15 meter antennas than 12 meter antennas. It is a contest band so more important to be BIG on 15 than 12.

OK, good reasons. I'll go with that thanks.

What about 20m?  It is open far more than 15m.

Well, a local ham told me he stays away from 20 M because of all the nets and crowding.  Sad

One person's opinion. Here's another: 20 meters is great. Probably my single favorite band, if I had to choose.

Skip 12m & 15m and get on 20m, more consistant contacts will be available, there is No issue with Nets & so on.

If I was limited to one band only, it would be between 40m and 20m. 15m and 10m would not even be considered.

I want to further add that if you put up a 40m dipole you will get 2 for 1 in that it will load on 15m as a 3/2 wave antenna. My first Novice contact in 1969 was on 15m using a 40m dipole.

15 meters has more activity; but I like 12 meters better because it is much less crowded and I don't have an amp or a beam.
If you like to try and work DX, you will have far better luck (pun intended) on 12 and 17 than on 15 meters when it comes to getting thru pileups without an amp or beam.  (for example I worked Wake Island on 12, but struck out on 15 and 20)

Another consideration is propagation.  12 meters right now is open everyday; when the sunspot cycle wanes it won't be open. 
So you can experience the 12 meter fun now while it is doing great things, or you can go with 15 which will see more openings when propagation dips.  Also, as someone pointed out, if you have room for a 40 meter dipole it will also work on 15 meters. 

Let us know what you do and good luck.

I somewhat disagree. 17 is a good band but very limited in size and 12 is open far less than 15 and 17 and 12 have less operators too. 20 can be bad at times with pile ups but not always and there is always a QSO to be had if you look around. 15 has a lot of space for QSO's even when band is open.

OK I've read all the posts so let me respond in toto. To clarify, I am going to put up a 40 meter dipole above my house, which I hope to work on in the next week, so that will be covered.

What I'm playing with is a setup I've had for several months, at the side of my house, rather low. Right now I have 17m and 10 m dipoles in a fan dipole configuration. I have had great luck with 17m (see my log on QRZ), and almost none with 10m, with the exception of the 10m contest period. Other than that, I rarely see any signals on 10 - so I'm removing that dipole - well, rather I'm adding wire to make it either operate on 12 or 15. That's what this is all about.

I'm going back and forth between 12 and 15 with my SDR spectrum display at 18:00 Z (now) and I see 8 QSOs on 15 and 1 on 12. Yes I know the time of day has an effect and so on, but I see more activity on 15 than 12.

I'm not discounting 12 as a good band, but I think given what's been said I still want to try 15 first (keeping 17 also). If I don't like it, all I have to do is trim the wires and I'll be on 12 in no time.  Wink

I agree, 15m  has way more traffic

If you tune 40 m antenna for about 7.1 to 7.15 it will resonate at 21.3 to 21.450. Antennas resonate in intervals of 1/4 wave, 3/4 wave,  and 1/2 wave, 3/2 wave, 5/2 wave etc. The radiation lobe changes but match is good. This being said, a 15 meter dipole is a bit redundant. Make it 20m instead.

I concur on the 20 meter suggestion as well, sure there are some nets 14.300 is occupied nearly 24/7 but so what? Its a pretty big band and I make quite a few contacts on it. That's what the big knob is for  Cheesy

ps; If your into digital 14.070 is one of the most active 'digital portions' of just about any band at least for me. Lots of activity and a heaping portion of DX as well.
