Say you put a high gain YagiLog to receive a signal,] Actually a LPDA (Log Periodic Directional Antenna) is limited to about 6 dB directional gain over it's frequency spread. That's due to it's deign to be usable over an octive or more of frequency with a pretty flat gain. The Yagi is able to be de...

One place I worked at did a test of a "passive repeter" scheme in down town Detroit for UHF two way radio. The customer had trouble reaching the company repeater with 4 watt hand held radios in a basenment. Our Pickup antenna was in this basement area of a 4 floor building and the High gain Yagi was...

Ceiling may be 4 ft higher than a desktop antenna = not much difference. Gotta figure out how to get on the building roof

Almost ANY full size, gain antenna for UHF will fit in most attics, get a rotor to turn it. Nothing special about an attic unless you have a metal roof or lots of metal (heating ducts, AC power wiring)up there already !
A halfwave dipole or EDZ is a bit wimpy for UHF reception !

I have a DX394. quite a bigger radio, AMBC to 30 MHz, AM CW SSB receiver.

I tried clicking on the "image but got nothing, maybe this forum prohibits image files /

OK, it's the local cable TV Co, head end tower ! That's why all the TV antennas, for local plrograming distribution and the big satellite ant on the ground for the other networks. I guesss the Independance Township FD took down their VHF antennas when they got on the Oakland Co digital comm system. ...

I have been in that area many times, know there is a tower at the fire station just up the hill from what you mentioned. The FRN registration shows it was there as early as 2016 . Will try google earth to see if that is the FD Comm antenna tower.

The rectifier tube may have been a good sub. many of the 5V filament dual diode tubes were using the same pin linup for the elements, only made physically different to handle more or less Plaate current and voltage. .

I get some pretty good FM DX when I plug my roof mounted, 30 ft dipole into the unmodified PL880. One Bay City station and WCMU from Mt Pleasant , almost any time of day

It's not the FM that can't use the ext ant connector, it's the AMBC and Longwave that needs a mod . You have to wind a few inches of wire around the main AM/LW loopstick and solder one end to ground and the other end to the connection for the ring part of the ext ant conector using a stereo plug. FM...

Don't kill the AM band with pure digital. Analog AM that can travel hundreds of miles at night when it all hits the fan needs to be kept. IF, and IF, they feel that they MUST have an all-digital AM signa, then limit it to one small section of the band: the X-band from 1610-1710 only. PERIOD. It ain...

I wonder if there will be any compatability with existing AM HD/FM HD receivers like in most automobiles and trucks built in the last 9 or 10 years ? Maybe this will wander from mode to mode of un compatble trasnmission types like AM stereo did ? Sounds like the swamp water is getting deep again ! A...

I have had a portable, handheld analog scanner for decades, like to take it on vacations and search for VHF and UHF traffic,. I had it programmed for the Marine freqs and in Hawaii and the FL Keys, I heard very little. On a short cruise I noticed a CB and a Marine VHF radio and asked the pilot how t...

With an analog receiver you can hear mostly the aircraft traffic , Railroads, and some fire departments and small business users that have not migrated to digi systems. If you live near water with commercial and serious amateur mariners and fisher men, you can hear some traffic on the marine channel...
