ham radio transceiver
A question about HF radio and antennas?
This question is about CB radio….but i could use some help from hams who use 10 meters for broadcasting also (the same physics pretty much apply)…..so i have a question about the range of a CB radio……i live in a place thats pretty flat and heavily wooded……I was wondering which antenna design will give me the most range out of my 4 watt transceiver…..The first design is a loaded 4 foot monopole mounted in my attic (keep in mind that my attics height is above most of the surrounding terrain and abstructions….also my attic has no wires or pipes in the ceiling and has thin walls)…..i know the attic walls will attenuate my signal slightly………the second design is the same antenna mounted on the ground (12 feet below my attic level) with a extensive system of below-ground radials…..so which one is better?
sorry about poor grammar
I would think that the attic antenna might have a slight edge. I assume it would have some sort of ground plane radial wires. Being elevated, the radials would not have
to be as extensive as an in ground setup. Other considerations: the in attic antenna is stealthier (your neighbors could not object to its appearance). Also it would not be exposed to the weather. On the other hand, the indoor antenna may cause havoc on
your phones, stereo, lamp dimmers etc. (because of close proximity to other electronics).

I won’t go into a lot of detail here about the individual used ham radios that you may find online,but I will tell you that I prefer the simpler, less expensive models like a Radio Shack HTX-212 2 Meter Ham Mobile. I’ve seen some radios like this sell for well under $100 in good shape, and I believe that the ratings on this particular machine are good (better check the ratings out for yourself just to be sure). I’ll admit that it’s a mobile unit and is probably not a high-powered, but it is a wide band receiver (136-174) and it can be fun to scan the local public service frequencies, in addition to its main function as a ham radio.
A Kenwood TR-7950 2 meter Transceiver Ham Radio might be a good choice as decent base unit, and might work out fine for someone just starting out in the hobby, but is probably more expensive than a run-of-the mill transceiver. But, you do get what you pay for, and I always seek out the higher-quality units, even if I have to pay a little extra. I’m rarely disappointed, though. With a maximum of 45 watts power,the Kenwood has 21 memory channels, a scan feature, and an auto repeater offset.This one I noticed was a bargain at under $150, and it was refurbished by a detail-oriented hobbyist. This is a unit that probably would have satisfied me.
Don’t be fearful of buying a used ham radio. Just be sure you are well-informed, ask lots of questions and definitely make sure you always purchase from a reputable seller.
