Hello Dave I'd be interested to know more about your disc dipole experiment, size and materials etc? A Google search brought up nothing. 73s Tracey G5VU

A better option to the discone is the bicone. Sure, it's larger, but behaves a bit more like the LP over frequency, but without the directionality. For his purpose, the discone may serve as the

I agree 100%, Dave. At least if directionality is the goal. Since the OP originally posted a vertical antenna, I presumed he wanted omni-directionality with flat gain over a large bandwidth. And if

I presume G is gain. Is that in dB or the numerical ratio before the 10log[ratio]? Dave - W?LEV [email protected]> wrote: -- *Dave - W?LEV*

The Schwartzbeck log periodic is by far the better antenna. They offer a far flatter response response and are directional. Directionality allows one to do a better job of finding RF emission

In general, a log-periodic antenna will give flatter gain response over a wide frequency range than will a vertical antenna. But the log-periodic antenna is more directional (in the direction of the

I am asking first about the PCTEL OP451 antenna, but also in comparison with, say, a Schwarzbeck USLP 9143 Log Antenna ( http://schwarzbeck.de/Datenblatt/K9143B.pdf ) As I need the antenna as a mobile

Anybody used PCTEL OP451 ( 450 MHz – 6 GHz, VSWR <2.0:1, 50 Ohm ) wideband antenna with TinySA Ultra ? It is a good match? Anybody had any experience with this one or a similar antenna? Pros and

Well that wasn’t very smart! ?Yes, I’ve found the correct page now - thanks.

You are reading the tinySA basic spec, try the tinySA Ultra spec -- Designer of the tinySA For more info go to https://tinysa.org/wiki

I'm trying to use the signal generator again, as I have many times.? But I'm looking for a bit more power than before.? I see that it is specified (at

Did you read the change log? -- Designer of the tinySA For more info go to https://tinysa.org/wiki

I 'll ask the question in a different way. There are versions in the tiny SA Ultra line ( ZS - 405 , ZS - 406 , ZS - 407 ) that probably differ in hardware. The latest versions of the software are

That's only with the FW release after the introduction of the Ultra+ If you run older FW there is no indication. Just tinySA Ultra, which means ZS405 -- Designer of the tinySA For more info go to

Hi in config, version, it is on the first line.....

These limits have indeed not been tested. -- Designer of the tinySA For more info go to https://tinysa.org/wiki

I agree with what has been said, done numerous updates no probs. Always do a self test prior to an upgrade, else if you have damaged the unit, you may think it was due to the

Hi. If you connect the tinySA Ultra computer to the tinySA APP program, you will see this information in the log window.

Generally as Clyde says make up your own mind. Once you have done on a couple of updates there is no stress, providing care and basics are considered. Always fully investigate that others that have
