grounding antenna pole drops reception

[ta240]

When I connect the grounding pole to my antenna pole I lose some of the weaker stations.


Does grounding the pole typically affect reception?


Am I connecting something wrong or since the antennas are clamped and thus basically part of the antenna pole is it just affecting them and there is no way around it? It is just an 8' grounding pole pounded into the ground next to the antenna pole and connected with solid 6 GA copper wire clamped on both.

I haven't yet grounded the cable itself to the grounding pole.

thanks for any info or tips.

Y5-7-13 antenna (into a 300 to 75 transformer) above a DB4E antenna into a VHF/UHF combiner and then a CM-7777 preamp then about 75 feet of cable from amp to TV
8' grounding pole next to bottom of 22' galvanized pipe which is strapped to two roof edges near the the top about 1' apart at different angles then extends about 6 feet above roof.

Please make and post a tvfool report for your location.

Use the Exact address to make the report.

Make the antenna height in the report 25 feet above ground.

You're not done until the coax shield is also grounded AND your new grounding rod is properly bonded to your structure's existing ground electrode system.

See NEC Article 810 for details.

The VHF antenna is an Antenna Craft Y5-7-13, The UHF is Antennas Direct DB4E

What is the make and model of the antenna??

Also please make and post a tvfool report for your location.

Agreeing with ADTech, if you have driven a ground rod near your new antenna installation, for safety reasons, it must be bonded to the existing electrical service ground system. Per NEC 810.21 (J) & (K), a minimum, #6 AWG copper is required.

A coax grounding block should be installed (preferably outside, close to the ground rod) and connected to the grounding electrode system with #10 AWG copper (or better). (810.20 & 21)

The Current Broadcast Tv Stations/Channels that are transmitted and received in the , USA , Canada , Mexico , are.

VHF low band channels 2 thru 6.

VHF high band channels 7 thru 13.

UHF band channels 14 thru 51.

Your location has receivable channels in All 3 Tv bands.

--------------------------------------------

To help find the problem , the following information has to do with the DB4e - UHF channels 14 thru 51 antenna , and Y5-7-13 - VHF high band antenna.

And now a question about what weak signal strength Tv stations are not received when the ground wire is connected.

As examples.

KUVS-DT , Real UHF channel 18 , virtual number (19.1) UNI.

KXTV , Real VHF high band channel 10 , ABC


--------------------------------------------

Also the coupler that connects the 2 antenna together on to one coax Must Be a , UVSJ = UHF/VHF Separator/Joiner.

Not a reversed UHF/VHF splitter.

I'm in the process of finishing up the grounding.

The problem is if grounding the antenna continues to reduce the signal strength I'll have to scrap the antenna project and go back to cable. There is a limited amount of tolerance from the better half I'll get over programs cutting out in the middle before we end up reconnecting cable.

[ADTech]

Grounding the mast and coax should be expected to have no effect on reception. If it is, that suggests that your coax cable downlead might be defective and has become an active element in the receiving system.
