Dipoles are easy simple and 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 lines.

Here's a chart  for dipoles from the 1962 ARRL handbook.
Strangely enough, the laws of Physics haven't changed in 50+ years??

COAX LOSS  link to Loss calculator
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 just fine.
the biggest problem using 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 F to PL-259 adapter.
you can save a bunch ($$) by thinking outside the box !! BUT its not nearly user friendly
as copper coax..

Here's Three pages of information about Diode, Transistor , and
three Pin Voltage Regulators,  stolen from a Russian Web. Someone
did a great job,  of course its not 100% , there are "billions" of transistor numbers out there,   but this might be a good place to start
your search if you need info..
Three Pin Regulators


heres a list of various Frequencies used by many different radio
services.  it covers LF to microwave, Cell phones, to Aircraft on HF, GRMS
Family Radio,  GPS ,  Boats, and lots of other stuff,  
check it out,  note tabs at the bottom for different services

for you deep thinkers,   this is a in-depth handbook about Impedances
This is a 152 page book, if you can understand even a little bit of it, your ready
for a PhD...

Keysight's impedance measurement instruments have been in the industry for
over 40 years. Optimized for your frequency range, measurement parameters,
accuracy, and your device or material, we offer LCR meters,
Impedance Analyzers ..
For most hams the current 'crop' of test equipment is priced out of reach.  However
Keysight  in the olden days was called  HP   Hewlett Packard.. They did and do make
some of the best test equipment in the world, and lots of the old stuff will do the job in style !

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.

minimum information needed :
1. your Call
2. your name and complete address. 
3. something that indicates 2 way radio contact... like
    "Confirms QSO WITH"  or my card says
    "This QSL card Confirms TWO-WAY radio contact with",
4. a place to write contact information about your QSO,
     his call, the date and the time in UTC , the frequency , the RST, and Mode.

optional :
for the county hunters, your county
weak signal VHF guys your Grid .
Some folks put their CQ zone &  IARU zone.

A place to request a card or to thank someone for sending their card to you .
see confusion below ..
YOU NEED TO SIGN your card when you send one out.

Note the extra info above and beyond the minimum ,
like his zones and club info, email,  a place for notes.

On both of these cards there is a place that seems to be a confusion point, that being
                       Pse   QSL   Tnx

If you need a QSL, circle Pse  for please,  put it in an envelope along with a SASE.
If you received his card in the mail, and are sending a reply   circle  Tnx.
otherwise , you will be replying in an endless loop !.
Circle one, not both,,    its please or thanks   not both.

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
QSL's.  There are several printing companys in pocatello that makes cards, if you ask.
most will if you show them what you want, .

you will notice I did away with the Pse and Tnx confusion  , the RST is preprinted since
in my opinion  it is totally useless information, however it is required  for many awards,
so its there. 
If I copied your call without assistance,   your in my logbook  its a contact ..
I also have more info on my card  than you need but the basics are all covered.
that is , again, the stations call, time and date (utc),  band , mode  and 59+.

REAL HAMS, have QSL cards.
I also use the ARRL   LoTW system too.
