Does antenna height matter more than gain? Though it may seem to be
paradoxical at first sight, the fact is that very often the antenna height above ground might matter more than its published gain when it comes to HF
band antennas used for DX operation. Long-range DX contacts on HF bands typically require long skips on optimally selected frequency bands for best results. To achieve this objective, the radiation takeoff angle (TOA) has
to be quite low. Especially, under low SSN conditions (as is prevalent at
the time of writing this post), when the ionospheric plasma densities are
low and the slab thickness is also less, the higher TOA signals might
penetrate the ionosphere to be lost in outer space. Low TOA signals from
the antenna provide us the best prospects. Does this mean that we need to search for some special kind of antenna with low TOA capability to deploy
at our QTH? NO! We dont Every antenna can be installed in a manner so as to provide low TOA, however, the user must be aware of how... Click Here to
