|Dipoles are easy
cheap to install, almost invisible and work good. They should be as high as
installed if possible in the clear away from metal parts of your house, and power
Here's a chart and for dipoles. dipole length chart from the 1962 ARRL handbook. Strangely enough this hasn't changed in 50 years??

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 you are using, the more you lose in the coax.
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 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 !!

WHAT THE HECK
what kind of coax is this ?

very thing you every wanted
to know about dB's and way more. take some time and look at the
headings and see if there isn't anything info you might learn.

|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. I use both 67 and 110 LB Bond.
information needed :
This card does all that. its a club card.
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
