I said a good antenna. I consider a good antenna one at least having the correct polarization, a gain figure more then 0dBi—in the right direction (in this case, omni with a good take off angle). It is the physics, particularly the long wavelength, combined with the constrained space that prevents anything but a poor compromise from being practical.And, if about physics! Sorry I`m too easy firing hearing that name, physics. I had tutoring physics more than 20 years, somehow, as my second job.Even if we take the full size (non-shortened) CLC or GroundPlane, the lambda quarter is 300/27/4=2.777 meters or with taking in account the V(F) at least 0.95 or worst case 0.66 we get the physical length the 2.64 or 1.86 meters. Even if the tip of the antenna will slightly stick out of the glass frame, antenna may be mounted on kronshtein some 10-20 inches outside the wall, and the tip of it for sure will not ticking into upper neighbour window in the windy weather.
Poorly. The antennas are very inefficient. They are close to whoever they want to talk to, and if not it will be a base station with a large antenna mounted very high.Well let me aks about Truckers?
Truck Drivers are not 5. Feet above a House how does the CB Radios they have work?
In the US, CB on 27MHz is limited to 4W. When I used CB (in the mid 70’s) the sunspot cycle was favorable. We had a large base station antenna at 60 feet in the air. I got a few miles coverage—or a few hundred due to E-Layer skip. Even from the mobile we worked stations hundreds of miles away. On the base station, I worked Europe on occasion.RE: Ya`akov
You are true about goodness. Because when (just small time ago in very end of eighties) every rich man walked around with pager, and mobile phone meant Nokia 150 or later Nokia 450 - box of some 10-15 kg of weight when pressing the tangent in car all the electronic watches started to show midnight - then I got somewhere the few 27 MHz stations from far-beating choffeurs. I had one friend then in Jelgava city while I was in Riga, thats about 40 km. No any even bad signal. Went out of Riga inboard, distance 37 km - wonderful traffick. Tried to put one at mum house just the diameter off my home, distance 10 km, the satisfactory traffic however much of disturbances. And thats with 25 W !!!
Are you sure it's not 5W max? I haven't bought any CB radios in recent years, but I believe all of my old ones were 5W. There are surely different rules for marine bands, but the handheld I use for my boat is 6W.In the US, CB on 27MHz is limited to 4W. When I used CB (in the mid 70’s) the sunspot cycle was favorable.

But for local coverage even the ⅝ wave vertical antenna at ~20m only measured its range in single digit miles most days.
