you will get just limited performance on 20M and up in frequency.
You will get basically no performance on bands down in frequency from 20M or
14MHZ
If you have stations very close by on 40 or 80/75M you may be able to
participate in round tables...again, if they are very close indeed...as in,
within 2 or 3 miles
If band conditions are extremely good, you may make an occasional contact on
20M, 15M or 10M bands.
You will have RFi issues, and you will have noise problems making receiving
difficult at best.
Not trying to discourage you at all, but you need to be aware of the severe
limitations of an indoor apartment style HF antenna.
They very seldom work for anything other than limited receiving on HF. Most
guys who use HF in an apartment can get the antenna outside on the balcony
or something...this at least gets the radiator outside the building. The
building is full of metal and all sorts of stuff that blocks RF from getting
in or out, along with electronics that create high noise level on receive
making it difficult to copy stations.
I had limited success using a hamstick style mono-band mobile antenna
clamped to the balcony railing on the fourth floor for a couple years.
It got me on 20M and 40M, but barely... I didn't make any contacts at all
unless the band conditions were very very good.
Unfortunately, this is one of those things where there is no way around
it...the wheel has been invented, and reinvented on indoor HF antennas and
while manufacturers still make them and claim all sorts of fantastic
results, at the end of the day, they just don't work well.
That said, if you are located on the beech in florida or some other south
eastern State, you may find you have reasonable performance even with an
indoor antenna. Angle of radiation, propagation and other factors come into
play making the circumstances more conducive to success.
That said, the best part about ham radio is that if you try something, you
may find you have results that don't match up to the accepted theory or
experience of others.
So, try it and see what happens.
Another antenna to check out might be the MFJ loop antenna...a bit more
money, but they work well even inside buildings, at least better than your
typical vertical.
