From the back of your HF radio to the base of your antenna, how many connectors does your signal pass through?  Include the radio, tuners, amps, watt meters, lightning arrestors etc.  So everyone counts correctly, treat every break as a connector (don't count bulkhead connectors or lightning arrestors separately)

I just did a little work on my antenna system and I'm almost embarrased how many of those damn things I have... I'll wait 'till some of yall post your numbers first

For my HF station, it's 14 to the antenna.

Radio, into lightning arrestor, out of lightning arrestor, antenna.


If I use my portable antenna, it's 2.  Radio and antenna.

Good God

If you ever have problems you're going to need a friggin Site Master...

I was feeling bad about 12, although it really should be 10 since one of them is nothing more than a splice.  Will ultimately probably be 14 (I intend to add a remote coax switch) or 16 (I really should have a thru line watt meter)

Transceiver - 1
Amp - 2
Tuner - 2
Bulkhead - 2
Arrestor - 2
Splice - 2 (type N)
Antenna - 1

All but the splice are UHF.  I thought about making everything else type N but you'll have so many UHF connectors (unless you change the connectors on all of your gear over or order stuff from Europe) so I just sucked it up.  Adds greater flexibility, anyway.

VHF/UHF is slightly better at 8, although I don't even own any non-handheld VHF/UHF radios.  I use it for a receive only antenna for my scanner.
Radio - 1
Bulkhead - 2
Arrestor - 2
Barrel connector for grounding at base of the mast - 2
Antenna - 1

The ground at the base of the mast is questionable but it seems to be best practice regardless so I did it.  Either way, that's still around 4dB of loss on 144 and potentially 8 dB on 440 (depending on who you ask, or what position I was in or how pissed off I was when I was soldering)

This thread makes me feel better

I must not be doing something right, I just have one cable of lmr 400 going from my dipole into my radio, so a connector on antenna and one at the receiver.  I leave it unplugged when not in use, and drop my dipole during bad weather.  Perhaps I need to tour some peoples shacks.  I guess I have a separate cable for the vhf/uhf radio but cable just goes to my attic antenna.

I would love the opportunity to put a precision load on the antenna end of that string and my VNA on the transceiver end.

How about the torque your signal exerts on my radio when it pushes it across my desk?

Ha, we always seem to have a pipeline between us.

Ahh, real basic station here.



VHF/UHF - 4 connectors.




HF - six connectors.




And maybe a half dozen in the parts bin...

22 PL-259s

Antenna --> lightning arrestor, 4
Lightning arrestor --> coax switch #1, 2
Coax switch #1 --> upstairs HF radio, 2
Coax switch #1 --> antenna tuner, 2
Antenna tuner  --> 1 kW dummy load, 2
Antenna tuner  -->  null bridge, 2
Null bridge  -->  100 Watt dummy load, 2
Null bridge  -->  coax switch #2, 2
Coax switch #2 -- downstairs 100 Watt HF radio, 2
Coax switch #2 --> downstairs QRP HF radio, 2

The null bridge dumps the output of the two downstairs radios into to the 100 Watt dummy load and looks at the impedance presented by the antenna tuner. The tuner is adjusted until the bridge indicates a null (50 Ohms). During tuner adjustment, ~ 1/8 Watt goes to the antenna if the radio is putting out 100 Watts. I've had a few stations come back to me  while I was tuning. IIRC, one or more were on the West Coast. Not bad for ~125 milliwatts. There's enough leakage through the null bridge to copy strong stations.

I built the null bridge back when radios did not have internal tuners or SWR indicators. It protected the finals from high SWR, and allowed tune up without creating (much) QRM. It is left in because I do some homebrewing, and it makes presenting 50 Ohms to the HB sets easy.

5 connectors from the radio to the antenna on tuned antennas, 3 on resonant.

I counted breaks in the cable, so back of radio (1) lightning arrestor (2) antenna (1) would be 4 total

Impedance vs. frequency.  It would be neat to see if any of the connections could be detected with the TDR function too.  It's fun to measure stuff.
