Dipoles are easy
cheap to install, almost invisible and work good. They should be installed as
high as possible - in the clear -- away from metal parts of your house, and
away from power

Quick thoughts: the longer the coax the more power you lose,
the LOSS also effects how much of the received signal you lose.
The higher the frequency, the more you lose.
Bigger diameter coax usually has less loss.
Knowing the impedance of your antenna and the coax is important.
A dipole is actually close to 75 Ohms. SO, you can use cheap RG-59
or RG-6 TV cable since its also 75 Ohms.
I (k0ip) used 75 ohm coax (RG-11) for years on dipoles, it works good.
the biggest problem with cheap TV coax is --- its not copper
and hard to solder to. Its best to make a good crimp with a F connector
and get an adapter.
you can save a bunch ($$) by thinking outside the box !!

|QSL CARDS Guidelines
First, if at all possible to have your card printed on a 3 1/2"x 5 1/2" post card card stock, not a piece of paper, something like postcard thickness. To make mine, I use both 67 and 110 LB Bond.
information needed :
Here is a copy of my present card, I make my own on my old trusty HP4
laser printer, sometimes not an easy task, and I am not sure its
cheaper than buying pre-printed
you will notice I did away with the Pse and Tnx confusion , the
RST is preprinted since
