TV antenna systems are almost exclusively 75-ohm impedance, while amateur radio equipment is 50-ohm. The two are not directly compatible, and trying to run two independent systems through the same line isn't worth the additional complication and problems.
A discone antenna is a great wideband antenna. I'm using one, too. Wideband antennas have one drawback: due to the wide bandwidth, the gain is low. Usually, almost no gain at all. For generic frequency browsing with moderate to strong signals, you will be fine!
What Are The Pros and Cons of Using Discone Antenna? The discone antenna is one of the few wideband omnidirectional antennas available. The vertical radiation pattern is extremely narrow, so antennas are most sensitive to distant signals rather than a nearby RF source, ideal for the hobbyist looking for optimal range.
23 kwi 2019 · I am planning to buy a Wellbrook ALA1530LN NA active loop antenna to use with my SDRPlay RSPduo and I was thinking of installing some sort of discone antenna for B200 to cover the 70MHz-6GHz frequencies to receive whatever is out there.
6 wrz 2017 · To use an end fed wire on VHF is to invite very strong AM broadcast band signals being present at your input all the time. Go for the discone. Save you connecting and disconnecting the antenna or switching it between the Hi-Z input and A or B just so you can use the broadcast band notch filter.
The Discone antenna is a prominent style for high-frequency varieties. Dividing the disc and also cone with an insulator will affect some crucial properties, particularly at frequencies close to the limits of this type of radio layout. Discone Antenna Poor Reception
12 maj 2014 · Making an indoor discone is a lot easier as it doesn't have to withstand high winds. Cheaper too! An indoor discone can be built out of coathanger wire. "I was surprised when I started to pickup CB radio in the 27mhz range even though the preamp itself says its cut off is exactly 50mhz!" …
