Title: I was looking for ideas on how to build a simple network analyzer to test antennas, filters etc. so I typed &quot;network analyzer schematic&quot; (without quotes) on Google Images and it apparently returned some results I was expecting, but clicking on a lot of results from the first page opened some subscription only websites with suspicious names nagging me to create an account to see the actual images, some of which I&#x27;m 100% sure I already have seen on their original authors websites.
Those websites are clearly made by the same entity, and to me it appears they&#x27;re essentially hijacking Google Images results for their profit.
Here are some of those results; many more on the 1st page. I had a hard time finding something that returned an actual loadable image or an article without asking for subscription.
Note that they all return URLs containing &quot;spectrum analyzer schematic&quot; although I searched for &quot;network analyzer schematic&quot;.<p>http:&#x2F;&#x2F;yyrfm.microdeo.de&#x2F;spectrum_analyser_circuit_diagram.php<p>https:&#x2F;&#x2F;4.twizer.co&#x2F;rf-spectrum-analyzer-schematic.html<p>http:&#x2F;&#x2F;5.6.gvapor.nl&#x2F;rf_spectrum_analyzer_schematic.php<p>http:&#x2F;&#x2F;18.10.ulrich-temme.de&#x2F;spectrum_analyzer_schematic_symbols.php<p>http:&#x2F;&#x2F;4.3.beckman-vitamin-d.de&#x2F;vcr_tuner_based_rf_spectrum_analyzer_schematic.php<p>http:&#x2F;&#x2F;18.10.ulrich-temme.de&#x2F;spectrum_analyzer_schematic_symbols.php<p>http:&#x2F;&#x2F;2.4.wohnungzumieten.de&#x2F;gbppr_1_ghz_spectrum_analyzer_second_local_oscillator_schematic.php<p>http:&#x2F;&#x2F;5.6.gvapor.nl&#x2F;rf_spectrum_analyzer_schematic.php<p>http:&#x2F;&#x2F;13.1.starpartybus.com&#x2F;lm3915_spectrum_analyzer_schematic.php<p>Edit: it appears those pages are being slowly buried by legit results, but some of them still surface although much deeper.<p>Examples:<p>http:&#x2F;&#x2F;3.17.tierarztpraxis-ruffy.de&#x2F;pna_x_block_diagram.php<p>http:&#x2F;&#x2F;10.10.artatec-automobile.de&#x2F;block_diagram_power_antenna_wire.php<p>http:&#x2F;&#x2F;9.20.wohnungzumieten.de&#x2F;logic_probe_with_sound_circuit_schematic.php<p>7.12.gvapor.nl&#x2F;dds_function_generator_mcu_schematic.php<p>Note that I searched for the same exact phrase as above.
