Although I used someone's frequency counter back around the 1970s, I
never owned one. From what I recall, back then, there was a BNC
connector on the unit, where test leads connected and were used to
determine the frequency within a radio stage, or used to check the
output from a signal generator.

I'm looking on Ebay and seeing some costly ones selling for $100 and up,
which have lots of buttons and connectors. -OR- seeing some that are
listed to go from 1 CPS to 70 or 80 MHZ, which tells me that they can
show audio frequencies, and up to the 70 or 80 MHZ limit, which means
they will work for AM radio, many Ham bands, CB radio, but *NOT* FM
radio.

Then what caught my eye were these inexpensive handheld ones, such as:

However, these do NOT have BNC connectors. Just an antenna. (No test
lead connector), So, obviously, they can not read audio freqs, and can
not be used to check the stage in a radio, but should probably pickup
the output from a signal generator if the sig gen test leads are held
near the antenna.

However, this device (above URL) only covers 50 MHZ to 2.4 GHZ. That
means it's worthless for AM radio, CB radio, and many lower Ham bands.
(In my case, this would be pretty useless, since I mostly work on radios
that are AM FM CB or SWR.

Ideally, something that covered 1CPS to 110 MHZ would be best suited for
my needs, but I cant find anything like that, at least not in the price
range of $50 or less. (which is what I am willing to pay for something I
wont get real much use from).

My antique Eico 320 Signal Gen only goes a little over 100 MHZ, so once
again, the example URL I posted would not be real helpful.

So, I am pretty confused. What's better, an antenna or test leads?

Do they actually make and sell LOW PRICED Freq Counters that go from 1
CPS to 110 MHZ or so?

Then again, it almost appears that to get full coverage of all
Frequencies, a person needs to buy TWO Freq counters, since UHF TV
covers the 470 to 806 MHZ. But once again, what good is a Freq Counter
with no test leads (just an antenna) for use on television?
