Gray Hoverman Antenna

[Admin 2578]

This project is dedicated to Doyt R. Hoverman (b.1913), the man who created and did the early work on the Hoverman antenna at a time when antenna modeling programs did not exist. His work would have been entirely created and improved by field testing, trial and error, and with a great amount of calculation without the benefit of electronic devices. Without his efforts, our work would not have been. Doyt Hoverman passed away in December, 1989 at Van Wert, Ohio, USA.

For the impedance adaptation (300 Ohm> 50 Ohm or 75 Ohm) the following variants can be used:

 

 

 

on PCB #1,5mm

great  ! JOMY can you simulate it for 1800 lte  ?   its simple  and gives high gain

Hi can I use gray hoverman antenna without impedance 

 

 

[Admin 2578]

I don't understand exactly what you mean...!!!

[Rtyon 1]

I mean can I use the Gray hoverman antenna  as wifi antenna without impedance I mean omit the impedance 

[Admin 2578]

,,,why don't you read this post carefully,,,?

Hello! After reading about Gray-Hoverman style antennas and how to do antenna, I will show you a new design plans, and assembly details available at "The Jeffrika7b Antenna"

The Jeffrika7b is designed for a bi-directional, horizontally polarized reception patern over the two ATSC bands, VHF 7-13 (174-216 MHz) and UHF 14-36 (470-608 MHz), with an impedance of around 300 Ohms.

a Mesh wire REFLECTOR would give at least 3 dbi more...and tailor the impedance...down to 75 ohms...MAYBE...

in Meters...?

8 AWG = 10 mm2 Copper...

Tube is PVC 3/4

,,,,yah,it"s no so good...

[clanon 258]

maybe gets better with thick copper wire and SMOOTH rounded Bends...they look to angled ...imho
