Broadband TV Antenna Design

The simple broadband TV antenna works at the 580- 760- MHz. Passband of the antenna is 180- MHz. Antenna has input impedance 300- Ohm at the pass band. 
The Design also can modified from  Band frequency 470-806 and with impedance 50 Ohm.

Antenna may be used with antenna amplifier that has such input impedance. Antenna may be used with coaxial cable with broadband transformer. The antenna is critical to any nearby metal subjects. Place the antenna with isolator connected to Antenna body and tower or antenna holder.

They can destroy the DD of the antenna. Space in 50 cm near the antenna should be free from such metal or conductive subjects. If antenna is used for reception purposes the best way is place low noise amplifier at the antenna terminal. 
LNA or Low Noise Amplifier can be made with 2SC3358 or 2SC3355, Low Noise Wideband Amplifier 0 - 1 GHz

Digital TV Antenna Outdoor

According to frequency range of the Digital TV Outdoor Antenna :

For Band VHF : 170 MHZ - 230 MHZ, Which is  television channels 7–13 (VHF-Hi), known as "Band III" internationally. A number of DTV channels have begun broadcasting here, especially many of the stations which were assigned to these channels for previous analog operation.

The U.S. FCC allocated television broadcasting to a channelized roster as early as 1938 with 19 channels. That changed three more times: in 1940 when Channel 19 was deleted and several channels changed frequencies, then in 1946 with television going from 18 channels to 13 channels, again with different frequencies, and finally in 1948 with the removal of Channel 1 (analog channels 2-13 remain as they were

For Band UHF : 470 MHZ - 860 MHZ

Australia

• UHF citizens band(Land mobile service): 476–477 MHz
• Television broadcasting uses UHF channels between 503 and 694 MHz

• Canada

•  470–806 MHz: Terrestrial television (with select channels in the 700 MHz band left vacant)

• United Kingdom

•  470–862 MHz: Previously used for analogue TV channels 21–69 (until 2012).

• Currently channels 21–35, 37 and 39–60 are used for Freeview digital TV.^[6] Channel 36 is used for radar; channel 38 was used for radio astronomy but has been cleared to allow PMSE users access on a licensed, shared basis.
• 791–862 MHz,^[7] i.e. channels 61–69 inclusive were previously used for licensed and shared wireless microphones (channel 69 only), has since been allocated to 4G cellular communications.

• United States

• 470–512 MHz: Low-band TV channels 14–20 (shared with public safety land mobile 2-way radio in 12 major metropolitan areas scheduled to relocate to 700 MHz band by 2023^[11])
• 512–608 MHz: Medium-band TV channels 21–36
• 608–614 MHz: Channel 37 used for radio astronomy and wireless medical telemetry^[12]
• 614–698 MHz: Mobile broadband shared with TV channels 38–51 auctioned in April 2017. TV stations will relocate by 2020.

What Purchaser said about this Antenna  ?

This Antenna Digital very Excellent for Outdoor use. You assembled the antenna by hand using the enclosed directions, easy no tools needed. Powered and tested the rotation/motor of the antenna in the house, worked as expected (didn’t use the remote as I didn’t have batteries, used the dock). Grabbed my ladder and tools with additional wood screws and washers as the package only contained 2 wood screws (not enough if you ask me). Climbed on to my roof and mounted the bracket on the side of my chimney tunnel exit than mounted the assembled antenna with pole. Ran the antenna’s coaxial cable down the side of my house and used a flat coaxial jumper cable to get it through my window seal into my house as I did not want to drill through my wall. Once I plugged in a second coaxial from the window flat jumper cable inside my house to the antenna power box and a third coaxial cable from the power box to my TV, I was in business... I troubleshooted the antenna rotation using our favorite channel that used to be fuzzy and studdered until I got great reception. The great news... once our favorite channel was in perfect reception, I used the settings on my TV to auto save all view able channels and now I have a TOTAL OF 54 CHANNELS (we live in Belton MO) that my family and I can watch!! That’s a win if you ask me. We had under 10 channels that stuttered before with our typical indoor antenna. Now to see how far it holds up and see how well it works during bad weather like rain and snow, not so sure if the material would hold up in Arizona sun but will be willing to try when we move back.

Another Purchaser commented :

I have tried many antennas, trying to get a TV station my wife wanted, and finally found it. Great antenna, easy to put together. I had a problem with the control box, but the customer service was great. I was very impress how quickly customer service answered all my questions and made sure I was happy with my purchase. I can receive 102 channels that is 2x more than all the other antennas I have tried. I even tried an antenna that cost about $200.00 bucks and this antenna is 2x better. I like that the antenna comes complete. Coax, pole. control box, remote. No extra wire is needed for the rotate function. Assembly is easy the antenna snaps together. Im a very picky guy, and do not normally give 5 stars, but this one really deserves it. I give the antenna a 5 star and the customer service was fantastic it also gets a 5 stars.

Not Sattisfied Purchaser commented about this Antenna :

 The service department was excellent. Quickly answered my email. We did some troubleshooting which did not correct the problem, so they sent me a new upgraded model at no extra charge. So far it is working fine. I would recommend bc if there is a problem the service team will take care of it promptly.
Original problem
WA 2608 150 mile range antenna. I have had my antenna hooked up 6 days. Assembly was easy. Installation instructions were clear. However after I installed it and used compass points to aim it, I ran a scan I did not pick up channels 65 miles away (per antenna point app and antennaweb), I did however get 29 channels from closer towers. Tried running scans at different times of the day and night to see if that effected anything bc a few of the channels would go in and out while watching a program. Then it just quit picking up any channels at all. Tried multiple scans but got zero channels. Emailing Service Team.

Why 50 Ohm Impedance cable Ideal for Transmitting RF Signals ?

Inspired by Rodrigo , one of this blog reader, who ask about why used 50 Ohm impedance ?

The answer can be shown in the graph above. This was produced by two
researchers, Lloyd Espenscheid and Herman Affel, working for Bell Labs
in 1929.


They were going to send RF signals (4 MHz) for hundred of miles
carrying a thousand telephone calls. They needed a cable that would
carry high voltage and high power. In the graph below, you can see the
ideal rating for each. For high voltage, the perfect impedance is 60
ohms. For high power, the perfect impedance is 30 ohms.


This means, clearly, that there is NO perfect impedance to do both.
What they ended up with was a compromise number, and that number was 50
ohms.


You will note that 50 ohms is closer to 60 than it is to 30, and that is
because voltage is the factor that will kill your cable. Just ask any
transmitter engineer. They talk about VSWR, voltage standing wave ratio,
all the time. If their coax blows up, it is voltage that is the
culprit.


So why not 60 ohms? Just look at the power handling at 60 ohms -
below 50%. It is horrible! At the compromise value of 50 ohms, the power
has improved a little. So 50 ohm cables are intended to be used to
carry power and voltage, like the output of a transmitter. If you have a
small signal, like video, or receive antenna signals, the graph above
shows that the lowest loss or attenuation is 75 ohms.


Still, I get a lot of feedback from people who use 50 ohms for small
signals; you can see above that they are taking a 2-3 dB hit in
attenuation. Excuses I hear are “It's too late to change now!” or “That's the impedance of the box itself.”

This is especially true of most test gear, which is universally 50
ohms. You have to buy a matching network to use it at 75 ohms or any
other impedance. But there are lots of applications where 50 ohms is the
best choice.
